[Q] Launcher Pro jitter with MIUI 1.3.18

i recently installed MIUI 1.3.18 along with launcher pro, however i noticed that when i try to scroll through my list of apps, the icons simply jitter up and down very quick and they do not scroll at all.
when i scroll between homepages, its butter.
ive tried reboots and clearing the caches to no avail. im not sure what could be causing this.
any help or insight would be appreciated.
TIA
figured it out... it was the 3D app drawer apparently causing the jitter... hence the EXPERIMENTAL warning...
that was such a bush league mistake, im not really sure how i missed that one lmao

well at least that were on the subject of MIUI, can anyone confirm that the CPU option is gone in 1.3.18?
i saw it on older versions and when it was enabled, my evo was fast as hell
but now in the new GB version i cant find it

touchwiz micro stutters

Hi guys I got my Rogers Galaxy S3 2 days ago (i747M). For the most part it is buttery smooth. But I notice that sometimes touchwiz has some micro stutters when moving between home screens. I also notice that while switching between home screens, before entering the home screen that has the Gmail widget, theres a quick minor stutter. Can anyone replicate this?
The way I did it was, first use the internet browser for a bit then go back to the home screen. After start moving between home screens and see if you have and stuttering before entering the home screen with the Gmail widget.
Is this a problem with the widget?
Extra information: I am on stock, un-rooted.

This is normal. I also experienced this with stock ROMs. Something that will help mitigate this issue is if you flash a custom ROM that has the scrolling cache disabled (such as Kyan ROM. There are others, but I know this one off the top of my head because I have personally used it). Though they do not go away fully even with the new ROM, the fluidity of the interface if greatly increased.
The only way that I know of to make this go totally away is to flash AOKP or CM10 as they have implemented project butter with great success.

This may be a bit off topic but, I know nightlies for CM10 are out.. But do you think we will get the stable version of it? I notice for CM9 we didn't get the stable version.. That kinda worries me a bit because I like cyanogenmod and the progress they made with CM10.

I wouldn't worry about it. We haven't gotten a stable version of CM9 yet because the Galaxy S3 came out after CM was well into its development cycle. Also, with the release of Jellybean source code, there isn't a huge incentive for the CM team to continue working on getting a "stable" build released (stable is in quotes because a lot of their nightlies are actually pretty stable). I have been running task and ktoonsez's AOKP for a while now and I have to say that their 8/20 version is quite superb. It offers much more customization that CM10 currently has and I would highly recommend it.

Yes I have this issue as well, I also am flashed on KyanRom, there isn't as much stutters, but they still happen here and there, even when I close an application, sometimes my widgets on the page it goes to look as though they've disappeared, but come back. I also experienced this while being unrooted. So far, don't know anything that can fix the issue to the fullest. I think lowering down on the amount of widgets on the home screen can help. But who doesn't love widgets?

Guess will have to wait till Jelly bean comes out. I'm sure project butter will get rid of 99% of lag and stuttering.

[Q] AOKP JB Build Problem with 240 DPI

Hey guys, I have been an AOKP user since long. Have been using their Milestone6 until they released Jellybean builds.
Must say I am purely satisfied with these builds but have a small problem with this...Right now I am on JB Build 4.
I am getting tabs in two rows if I change the dpi of my phone to 240 or lower than that. 260 works fine though.
This never used to happen in Milestone 6. I am a 240dpi user and loves to see everything in one screen, but these two row splitting is annoying.
It happens in all the apps based on HOLO UI like Phone, People, Boid(3rd Party), etc.
Attached are the screenshots to explain my problem.
I tried looking into build.prop as well, but didn't find out what's the problem. Before reporting to AOKP guys, I want to ensure if this can be solved and this is seriously a bug or not!
Please help.
P.S: Landscape view doesn't have any problem. The problem persist only in portrait mode. However, Milestone 6 based on ICS never had any of such problems. Also, I know AOKP JB builds are still in their preliminary stage but this problem is a small things which I think need to be reported!

Use 241.
No visible change in applications other than fixes.

Thanks alot

Why do you like your ROM?

What rom do you have on your phone?
Why do you like it?
What dont you like about it?
Im curious to see what everyone is running
So far ive ran aokp, paranoid android, and cm10.
Im currently on cm10 and enjoy how professional it is. (explaining the swag button to potent galaxy buyers was kind of tough)
I would have kept paranoid android but the profiles didnt work and i didnt know how to use the dpi changer.
I also started this thread to see who uses android development ROMS instead of the original development ones
Im mainly interested in the non original android development roms users and their oppinions but everyone's answer is appreciated

My favorite was Codename Android, besides one major flaw that myself and very few others experienced: Impossible to send SMS longer than 160 characters, regardless of settings/reflashes/apn/etc. Just because it was the smoothest ROM for me.
I value UI smoothness above all else and have yet to find a ROM that is truly stutter free.
CM10 is ok, but if you go to clock and swipe to the side to go to timer it stutters like a pentium 2 running Crysis: Warhead.
Stock ICS ROM's lag, as well Facebook/third party app scrolling has constant stutter reminiscing of SGS1
JB Leaks (LIF, LIG, LIH) give me blackscreen reboots once in a while, although noticeably smoother than ICS.
I didn't mention battery life as quite frankly I can get a day of usage with every ROM I have tried so far which is nearly all of them.
I think I'm using stock ROM right now as I was fed up and just restored an old nandroid... I guess its ok, everything just works, lots of stutter's though. Doesn't have that premium feel you expect of a device at this price point.

Run AOKP then, it's extremely fast and smooth.

I have tried multiple versions of it, still stutters on homescreen sometimes. Same Timer stutter as CM10 and annoying alarm bug (although there is a fix, it's inconvenient). As well the Nova launcher that AOKP uses, and pretty much all third party launchers have a little input lag due to non native integration or no hardware acceleration (not sure which, but the input lag is there).
Anyway I'll take my fluidity rant somewhere else, people seem happy with the current state of the phone.

The childishness of aokp turned me off since i looked at the boot logo but my gripes can all be easily fixed /hidden.
I havent noticed the speed difference but i do see tge lag you speak about but ive dismissed it as a hardware being underpowered to the rom issue and dont notice it as much anymore
So im still looking for answers from non original development users but to everyone else

Here is a quick look at some of the differences

Blazer Rom.
It's minimalistic, faster than stock without overclocking, great battery right out of the box, and EVERYTHING WORKS. take that jelly bean.

Because its my ROM. There are many like it, but this one is mine.

I'm currently using cm10 and I find very awesome. It's fast and has a lot of great features. I tried AOKP and decided that IMO cm10 was closer to actual 4.1, but AOKP had many more features.

I had been running AOKP for a week or so, I like its customization better than that of other ROMs.
I just yesterday found a new ROM called Paranoid KANGdroid. It pulls from CM10, AOKP, and Paranoid Android. Has pretty much all the features of all three. So much customization, I love it. Not fully stable, though, its only a few days old.

Weird notification drawer lag on any 4.4 based ROM

I have this really weird lag when I'm on ANY 4.4 based ROM no matter what kernel or gapps package I use. So I install the ROM and its all great but I start travelling and after sometime the notification drawer is all laggy and stuttering like never before. I thought it could be a GPS issue and tried disabling wifi, gps and mobile data but no luck, I also tried clearing app cache, doing a clean wipe and reinstalling ROM, trying almost every 4.4 based ROM out there. All I did was do a Clean install (factory reset, wipe dalvik, cache, system) from TWRP 2.6.3.2, configure the accounts, install superSU from playstore and update binaries, install TiBackup and restore user apps with data. It was still smooth until I leave work/home/travel somewhere. Anyone else facing this issue? Other than this weird lag, the UI is buttery smooth (no lags on homescreen, app drawer, opening and closing apps, etc) and even the RAM usage is quite low (<300MB). I cant seem to figure out what could be causing this. Please help me.
PS: the notification drawer lags ONLY when there are no notifications or when there is a permanent notification. When I get a dismissable notification it doesnt resemble any lag at all!
Thanks.

Is it only with 4.4 ROM's?

I'm also on a recent nightly, and although I don't *feel* any disturbing stutter in notification drawer, it isn't quite as smooth as what's on my Nex4. Now, as the OP has hinted, I tried getting a dismissable notification in the drawer and boom, the drawer is suddenly as smooth as hell - but only for seconds. Wondering why...

I have loaded app and stuff and i still have not seen any sort of lag.
When you are flashing are you wiping the device correctly it may still have files that will slow it down.

I do a clean flash as I stated previously. Factory Reset, Wipe dalvik cache, system, cache, Flash ROM, Gapps (dhacker29's latest), and reboot. Since I use TiBackup to restore, I also download SuperSU from playstore just to update binaries and make TiB work, I uninstall superSU after that and use the built-in superuser app.

I got that problem too!firstly i thought i was a bluetooth issue as i turn on the bluetooth and the notification drawer become laggy.but after a while i found it laggy continually even if i turn off the bluetooth.it's really a annoying thing

I know right? Once I disabled Wifi optimization as it was on, and it got smooth again, but that wasn't the end. I went to work and pulled out my phone, and boom, its all laggy and stuttering again. A few hours back I gave KitKat another shot but this time it was laggy even after the clean install without any apps restored. This is the weirdest thing to ever happen to my GNex. Now I'm back on AOKP 4.3.1 M1 with Tiny Kernel 5.4 with the smoothest android experience ever. Let's wait for the developers to take a look into this issue. :fingers-crossed:

Okay I think I found a solution. I tried 5 use-cases:
Flash method: Clean - Factory reset, wipe dalvik cache & cache, wipe ROM, flash ROM, gapps
1. CM11 ROM with built-in kernel
2. CM11 ROM with Tiny 5.4 kernel
3. CM11 ROM with built-in kernel
4. CM10.2.0 (stable) ROM with built-in kernel
5. CM10.2.0 (stable) ROM with Tiny 5.4 kernel
I noted that when I did not flash a 3rd party kernel the issue seemed to persist even at first start-up. But when I flashed a 3rd party kernel (be it any compatible kernel) there was absolutely no lag at all. But then the question of why I tested it on CM10.2 ROM is because I found the same notification drawer lag on CM10.2 (official) ROM. Maybe this started after the ram-disk was changed? (I'll leave that for the developers to decide).
Note: I'm currently on Gummy 21-12-13 build with Tiny 5.4 kernel, ART enabled. When I started off to work today I wanted to switch to 3G and when I did so the lag was back, but after it found a signal tower it disappeared. I have found no lag so far.
Something off-topic : But commonly throughout these tests, I found that these ROM's exhibited terrible lag when using live wallpaper.
If someone (facing the same issue as stated in the OP) can confirm that the above solution works, it will help alleviate the problem.
Edit: Also found in tricksterMOD that the deep-sleep mode was in the 'unused states' category.

Bump
Okay I guess the problem hasn't been quite solved yet, bumping so people can have a look at this.
Update:
In the recent builds notification drawer lags only when I'm not on Wifi no matter what KK ROM+Kernel combo I try.

I'm on CM11 with Fancy kernel. I also see the lag when not on wifi. It really has not bothered me. The KK ROMs are still fairly new, so I would just give it some time.
Break me off a piece of that Kit-Kat ROM!

I just wanted to confirm if it was really a bug or something that was specific to my phone. That confirmed the former, thanks!

Just wanted to add my thoughts on this. Are you guys using the Google Experience launcher with the "Ok Google" Hotword Detection? If so, turn off the hotword detection in settings. After doing that, I get no lag whatsoever in my notification drawer. I didnt use that feature that much anyway.

Still no dice on this issue? Not intentionally bumping, but I think this issue might have a deeper cause that requires more attention from devs.
I've read through the "suggestions" above and I can say that nothing works. What I have is a VERY clean CM11 + Franco r395 - no Gapps, no Google Experience Launcher, no Google Now (Google Search is force stopped and its shortcut removed), very few installed apps, no background apps except for input method, lots of free RAM (~520MB), yet this still happens. Only thing that removes the lag temporarily is an incoming notification, which only makes it smooth for seconds.

Okay, tried many JB ROMs and they all don't have the lag. Try one of the KK ROMs and they come back immediately. Something with KK source?
Sent from Google Nexus 4 @ CM11

One more update: flashed latest CyanogenMod nightly (CM11 20140325) and I surprisingly discovered that the notif lag is gone. Turns out I'm wrong, as the lag is gone only in lockscreen and Trebuchet. However, on second thought, does this phenomenon mean that CM/Trebuchet recently implemented something that potentially removes the lag? What patch is it exactly, and why isn't it applied on other apps?
I still think that this "simple and bearable" problem has a darker side that requires more attention.
