Softkey Animations responsible for lag. - Samsung Galaxy Nexus

Most of the lag on ics is caused by the soft key animations. There are some build of cm9 without these although they have been added back in this week. I think that they should be remove as they don't really serve any purpose and they usually look choppy anyway. They do in fact add significant lag to any animation that happens at the same time such as the app drawer closing or the notification pane sliding closed.

I am running stock on a Rogers GSM Galaxy Nexus, China batch. No lag here.
Your own experience is not equal to everyone elses.
Like when the Captivate got released, mine was buttery smooth, my wifes was a choppy nightmare.
Exchange your GN for another one if its so choppy.

Not true.
I have removed the animations entirely in our team rom. A lot of what they are blamed for is individual perception. They do not cause the majority of lag.

Laggy launcher & homescreen transitions

Anyone else notice that it gets a little jittery when you're on the app drawer and you hit the home key? When the icons do that zoom out, it's not as smooth as the rest of the phone usually is. It's minor, I know, but I'm starting to think maybe Apple has a patent on a smooth UI (that's a joke).
I've also noticed bad performance with live wallpapers on the home screens, it's really rough with most live wallpapers. I previously had the Epic 4G Touch (Galaxy S 2) and it was ALWAYS smooth as butter, even with live wallpapers... when running the stock TouchWiz UI. So while the processor/gpu in the GS2 is probably better, it seems to me like it's more of a software issue.
It doesn't bother me enough to want to go back to the Galaxy S II, mind you, physically this phone is superior and I sure love me some vanilla ICS... but are any of you noticing this with custom ROMs as well?
EDIT: I wanted to add, I've tried Nova & Apex, and I didn't notice a difference in this regard.
When you tried Apex did you turn on the setting that saves your home screen in memory? I have noticed almost zero lag with this option selected

It seems to help just a little with live wallpapers when sliding between homescreens, but it has zero effect on how jittery it is when you're in the app drawer and you hit the home button (when the icons "fly away" and you go back to the home screen).
I dont have any App drawer to Home lag.
Every stock LWP except "Phase Beam" lags afaik. Kinda sucks but how it is.

I will confirm that the zoom out animation when hitting home from the app drawer is not as smooth as it should be. My old Samsung Fascinate is on AOKP and the transition out of the app drawer is actually smoother than my Nexus. I wouldn't call it lag but it's definitely not as smooth as it should be.

On this phone, yes. On the Galaxy S2... no.
To contradict the apple joke, I have an iPod touch 4th Gen and my friend has an iPhone 4S, both of them get laggy transitions after a while, especially after opening a few apps. I'm on stock and have zero lag. Nova had less then apex from what I've used.

Same for me ..
The live wallpapers all lag, but its gotta be a software issue not yet fixed.
The app drawer fly away animation is weird, cause I do see that stutter sometimes. But then a lot of the time its smooth. Not sure what that's all about. But I'm of the opinion that everything can be smoothed with a software tweak.

These forums exist for many reasons including discussing problems, right? This is an obvious problem and I'd like to discuss it. Thanks.
Your solution here is to live with it or get a different phone and you've been "thanked" at least a couple of times for it. That's super constructive. Do you honestly not understand why I brought up the Galaxy S2 as a comparison, or do I need to draw pictures?
Am I the only one that finds it frustrating that Google's flagship device doesn't perform as well as other devices in something as simple as homescreen transitions or opening/closing the app drawer?
IMO its the soft key glow animations causing the "lag". There's a mod which I have done which shortens the length of the glow animations, its basically eliminated the lag you are talking about.

Nope it drives me crazy too. I have started using Apex launcher with the widgets tab hidden so its just apps and its better but still jitters a bit. I even get jitters and lag on the lockscreen. I turned auto brightness off which helped but from time to time it lags crazy if i swipe fast.
Its not good enough.
My friend and my wifes best friend have nexus s's and they perform a lot better than my Gnex with the stock launcher which is just embarrising.

So...what did you accomplish by bringing up the GS2?
Did you...fix your problem?
Did you...make yourself feel better?
We all get it, the GS2 doesn't lag on live walls. Well, guess what? This one does, like most android devices. This is a fact, and it may or may not get fixed. So really, bringing the GS2 into any conversation regarding the Galaxy Nexus is NOT constructive. Comparing the GS2 to this device is going to be met with irritated folks because we have been listening to it for the last 6 months. I am sure I am not speaking only for myself when I say I am sick and tired of it.
This is not a PC. We can't just go throw extra parts in it, and upgrade the hardware. Therefore, the only solution to your problem is another device. I am sorry if it offends you, but it is a fact. Take the good with the bad, or find another device that is better for you. This is how the smartphone world works.

So I figured out what causes the app drawer lag and FPS drops when entering & exiting

So I figured out what causes the app drawer lag and FPS drops when entering & exiting
Most of you probably won't notice it, but when pressing the app drawer, the frames kinda of drop and you can see it stutter, regardless of what launcher you're using.
The thing that causes the lag is the button glow animation on the navigation bar. Try for yourselves. If you have AOKP just go to rom control->navigation bar->button glow animation and set it to off or super quick. Play around with it and jump back to the navigation bar settings and set it to normal to see the difference. You want it at off for best performance. Now there is no lag or FPS drops when entering and exiting the app drawer.

This is an already discovered fix for the UI lag. Seems ICS struggles when layers are drawn on the UI. A good example would be when a toast notification is displayed, try navigating around using the phone and it will lag until the notification closes.
Personally I just set the glow to off as even with super quick it can still lag.

I just set the button glow animation to off. I actually prefer it set that way. So Win/Win!
For me, turning button glow animation off has no effect, even after a reboot. What I mean is, the glow animation is still there.
I've also noticed the lag/stutter when showing screen previews with the home button. However, I don't get any lag/stutter if I initiate screen previews with a gesture or other methods, only the home button.
Is this fix already included in any ROMs?
That's not a lag. Ever hear of animation? It takes a sec or 2 to complete. Is intended that way.

thank you adrynalyne, i was actually talking to myself, you just took all the fun and dispair away with not one, but 4 great pointers.
more seriously, i'm glad you took the time to awnser/search it. thanks.
If you are running CM9 or CM9 based ROM try enabling the 16bit transparency option and disable surface dithering. It makes absolutely no visible difference in quality but makes a huge difference in performance.
You know I've always wondered why there was this little Stutter/Lag whatever you wanna call it when I press the app drawer button.
I'am running AOKP and just took the glow off and while the animation will always be there, I no longer have that little stutter as it opens.
I was meaning to ask about this in some Rom threads, gingerbread app drawer always seemed so much faster opening. Since ICS is suppose to be better, I always thought, something wasn't right.
So much smoother. I'll take it.
I have noticed in ICS, when let's say you play a game, lets say Temple Run, you press on the volume keys and a pop up comes up, then the game shutters until the popup is gone, same thing when you have the keyboard up and you navigate the screen, it lags until the keyboard goes away.
Why is it like that in ICS?

Nah. Its some method which they wrote code that is not efficient prioritizing the toast message. Thinking about it, a toast message can originate from almost infinite sources as long as the app/process is running. So it may be too difficult to cleverly handle properly prioritizing toast pop ups in an efficient way. That's all I can think of.
I know when I wrote an app, it was very easy to put in any toast message I wanted anywhere. So who knows what the proper way is to handle them on a OS or kernel level.
I hope they remove this animation from stock android not only from our device but ice in general. It just looks poor and doesn't add any value.

[Q] Why does the notification bar lag in Jelly Bean?

So, I'll try and describe the lag. Supposedly, the Jelly Bean animations are all 60fps. But on the homescreen, when you pull the notification bar, I'm sure you will notice a slight (but still noticeable, at least 30fps) decrease in the smoothness. If you pull the notification bar with an app open (you can easily try it yourself, with the Messaging app, or even the Settings), it will be very smooth.
Is there a way to fix this? By overclocking the processor, the memory, I don't know, something like that? Can I flash something to fix this? I've tried searching everywhere, and people actually complained about it in some ROMs' forums (ParanoidAndroid for instance), but no dev seems to do anything about it.
TL;DR: I've been experiencing a slight lag in the notification bar, in ALL the Jelly Bean ROMs I've tested. Am I doing anything wrong?

I think this might have to do with the background going darker, as you pull the bar down. If you have a solid color wallpaper and drag the bar down, it will lag much less than if you have a picture as wallpaper, and I think this might happen because, when the background goes darker, you can tell it creates some banding, and that may result in the lag.
Anyway, just my two cents.

That's Jelly Bean, the notification drawer is definitely annoying and strange somehow, if you choose a custom background for it you can see that when you pull down the bar the wallpaper seems to scroll down cleanly and @~60fps, and the bottom bar (the one which changes color when you touch it) seems to run at a different framerate.
Someone must fix it!

I've disabled hw overlays in developer options and it is still laggy. This lag is still present in 4.1.2 (running CM10 Nightly).
In Flow's video review of Ice Cold Jelly 3.0 - AOKP, you can also see the lag present when he pulls down notification in the homescreen.
So the current information we have is this:
- notification dropdown lags only in the launcher homescreen and app drawer
- the dropdown is very smooth in apps
- some JB roms on other devices also experience this (GNex and SII) as reported in this thread
- the sense JB rom for One X doesn't have this issue
Do have any devs acknowledging the lag? does any rom's issue tracker have this?
When CM10 reaches RC stage we can find an official bug report
Many people are reporting notification bar dropdown lag, in AOSP based ROMs, and that in Sense-based ones this doesn't occur.
I know there are many kinks and bugs that need to be fixed on all ROMs, and that no ROM is perfect. But seriously, this one really annoys me, it takes all the fun out of Jelly Bean.
There's no Jelly Bean without Butter, and with this lag, it just looks like we're back to the Gingerbread ages.
If anyone could please find/suggest a fix for this, I'd be so, so grateful.
As people have mentioned, the notification bar is buttery smooth when there's an app open, but unless:
- The app is showing a dialog
- The virtual keyboard is showing
I've noticed the above while debugging my app (DataSync), but so far it seems to be an issue on all apps. To replicate try the following:
Open settings
Verify the notification drawer is opening and closing without any lag at all.
Tap "Performance", notice a warning dialog shows
Pull down the notification bar, notice the drop in framerate compared to the last attempt
Close the dialog
Pull down the notification bar again, notice it's once again smooth.
The framerate drop is less noticable with the keyboard open, but still there.
Is there any fix for it? or still no one working on it? Sometimes it is really annoying too see it, i had this problem with my galaxy nexus long long time ago, but when i took him now in hand it seems to be rly smooth.
I can't see any difference in the behaviour of the notification drawer if opening it while navigating the app drawer or while standing by in an app, whatever it is, or even when I drop it down from the homescreen. It's always 40fpsish. I bet it's somehow related to transparency which is completely unneeded and I cant disable it.
My question is WHY a single-core iphone4 notification bar drops down at 1000fps and a quad-core android device should draw it at 40fps.
Someone said "Lol wtf you complain about cm10 is in early nightly stage" well no man now it's stable and completely full of bugs anyway.
I'm subscribed to this thread so I'll still wait for a fix....
For me? cm10 is always in early nightly stage. I changed my rom to rd miui ics becouse of battery. This room is pretty fast, looks good for me. jelly bean roms on galaxy nexus looks much better then ics becouse everywhere we have 60fps. if on onex jb roms i haven't always 60fps i don't need it. I will wait for stable version. jelly bean with standart or bricked kernel, 10h work with 2h display and i havent battery, here i have 16h and 3 h display and still 37%
I notice this a lot myself. Compared to my mother's iPhone 3GS running iOS 5 and my cousin's G2 (Desire Z) running AOKP ICS, the notification shade on my phone is really damn slow. I wonder if this was done intentionally by Google to keep a consistent speed for the shade.
I had this too. Specially at the bottom part of the pulldown menu. It stuttered like crazy. Seems to been gone when I switched from ondemand governor to interactive with input boost enabled.

Solution for laggy homescreen and systemUI in 4.2.2 update

As we all know that the 4.2.2 update made our phone as fast as the 4.1.2. But it has a bug, at least for Maguro (not happening on my N7). Do you ever get a laggy scrolling on homesceen, when entering app drawer and scrolling in recent apps? I believe everyone has it. But only few people notice it. I have tried all 4.2.2 ROMs. AOSPA, AOKP, PAC, etc and all of them has this bug (I have done a clean flashing). And I have tried all launchers, Nova, Apex, Holo, Action Launcher, Stock, but the lag is still back!
The (systemUI) lag has to do with rendering (static) wallpapers. This can be solved by:
1. Setting a live wallpaper
2. Temporarily, by pressing the app switcher button, rotating the screen and pressing the back button
3. Disabling system autorotate
4. Making the launcher (instead of systemUI) handle the rendering of wallpapers. In Nova launcher, use the 'force scrolling' option, in Trebuchet (CM) use the 'wallpaper quick render' option
5.. Using an app to set static wallpapers as if it were a live wallpaper
Also, emptying cache for all user and system apps using Titanium Backup seems to affect the issue positively. Please note that this might result in some settings being set to stock (like the keyboard, snooze duration and some other minor things).
Well, this is only for temporarily solution for those of you that getting sick of this bug. Waiting for the fix from Google.

There's actually a lot of truth to the live wallpaper trick. Back on the Photon forums, we would use this technique to smoothen out the UI on our ICS and JB releases since we did not have a proper kernel and drivers, thus terrible onscreen performance. But this fix has existed since ICS! And it works!
Regarding the live wallpaper being smooth. It might have something to do with scrolling wallpapers too. How is everyone's feelings on a static, non scrollable wallpaper? Or is that what we are talking about?
I've had the choppyness too.
I am now using plasma beam and will report back. I also am going to try it on my nexus 10.
I'm telling you guys, try out the combo I posted in post 2. It really removes lag.

i use it like that(single homescreen no scroll)and i noticed the same lagging issue after a while
but i think it has to do with how you set the wallpaper, when i used zedge or image2wallpaper to set them the issue stated on the OP appeared
but if i use the stock gallery to set them and the problem is mostly gone
something else ive noticed is that the status bar lag only happens when on the launcher screen, open any app and pull the SB and its smooth, go back to the homescreen and pull it,its choppy

still happens even after using the stock gallery

I've noticed the same problem with 4.2.2 ever since it came out. I usually use Phase Beam so I never noticed it. Only when I switched to a static wallpaper (one of the stock ones) for a day did I notice that the transitions into and out of app drawer and scrolling through home screens gets choppy. I never did find a way to reproduce it reliably, but I do know that if you use it long enough it will start to happen.
Immediately fixes itself by setting to any Live Wallpaper as OP had suggested.
Problem only started to occur with 4.2.2. Never had it happen in 4.2.1 or 4.1.x.

I'm telling you guys, try out the combo I posted in post 2. It really removes lag.

Then try to swipe on lockscreen between widgets if you have some. You will notice that the lag is still there, but atleast its a better deal to have it on lockscreen then on homescreen.

I don't know man. I'm either lucky or just not as picky but I don't even notice lag there. I have a few screens of widgets on my lock screen too.
Set a static wallpaper, go back to home screen or lock your device. Then, swipe down the notification bar and notice how choppy it appears.
Now, go inside an application, like Calculator - swipe down the notification bar and notice how smooth it is.

I don't get it...

Ok, I see what you're saying now. It was slightly smoother. Thats odd.

[VIDEO] For those of you complaining about lag on 4.2.2

here you go.

rom: latest purity
kernel: ak kernel, rubix
nova launcher with "faster than light" animations and all other animations turned down to 0.5x.
A video with no details on how to help those people who lag on 4.2.2 doesn't really do anything for them.

edited op. i had lag on 4.2.2 with the stock launcher but once i installed nova and changed all the animation speeds everything changed to bullet speed.
Thanks for the video.
No offense but I don't think we're talking about the same sort of "lag". The one we're talking about is a system bug that came with 4.2.2. causes frame rates slowdown when scrolling between homescreens, lockscreens and in recents. When it appears you can even notice it while switching between the tabs in notification pulldown (gets really choppy). Problem appears randomly, sometimes after couple of hours, sometimes after a day or two. It cannot be eliminated by simple launcher change and turning animations off.
Turning animations off makes scrolling look faster indeed but it kills fluidity on the other hand which I really really don't like.

Rebooting, changing wallpaper, rotating screen (under recents) are known workarounds to temporarily get rid of this lag. Probability to reproduce the issue is lower when you did one/ some of them.
Workarounds aren't a fix for the sluggishness - it's still a workaround. And nothing is a workaround for worse RAM management compared to 4.1.2.
Hmm try opening a couple of tabs in browser (5+) and open the tab switcher and scroll. If you see lag, well done. If you don't, the flash 4.1 to see real butter. I can go on and on but the browser is the most apparent lag. Battery life too. Do not suggest me to flash custom kernels, been there done that. 4.2 is just a laggy mess all over. I've wiped, flash factory images, try out many roms even the rom OP is using. But none are as fast as good old 4.1
