Laggy scrolling and animations after screen replacement - Xiaomi Mi 9 SE Questions & Answers

Hello!
My phone has been left aside for several months because of a ghost touch problem, recently I had the screen replaced in order to fix the problem, but now I have a problem with choppy scrolling animations. The screen seems to be running fine at 60hz (refresh rate test and youtube videos), performance in games also seem to be fine. Is there any fix for this?
Thanks!

Did you get the original screen? If you didnt get the original display, that might be the issue.

Fix rotation lag?

I found information about the epic on this issue but not the epic touch. I have a lot of lag when I turn the screen sideways and when I turn it back. It take 2-4 seconds for the screen to change. I know it does it much faster as I have seen it on other ET's. I have calibrated it and it still has the lag. Any ideas what might be causing it that I can fix?
I really wonder if this will be improved with hardware acceleration via ICS update when that happens.
This is frustrating me more than the infrequent LOS that I have. It doesn't matter what launcher I use. I have tried the touchwiz, ADW EX, SPB Shell 3D, and LauncherPro. They all have a horrible lag when going from portrait to landscape. Now here is the other part of the mystery. If I go to gallery and open a picture, it switches from portrait to landscape really quickly as long as I am viewing the picture. When I back out it is back to the same old lag.
I had the same issue. I fixed it by doing the horizontal calibration in the display settings. Now my lag is at Max 1 sec.
Sent from my SPH-D710 using XDA App
I have done that and it speeds it up for a few hours and then the lag is back again.
Rotation lag isn't an issue for me, I have the opposite...the phone likes to rotate around anytime I tilt it at all. Very irritating. I just keep rotation locked so I don't have to deal with it.

Screen Tearing/Lagging while scrolling

My N7 fell in water the other day and even though there are no issues with the tablet itself, I'm not sure if the touch screen was damaged or not.
Whenever I scroll on a page or app, it looks like the screen is tearing or lagging and it seems like it's take a split second to catch up with the scrolling. This doesn't appear to be the case with watching video though as playback appears fine.
I'm running 6.01 on the Pure Nexus Rom, in case it's software based but I don't think it is as I was running a different 6.01 rom prior to that with the same issue.

Smoother digitizer (scrolling) on Android 9?

When I got my 5T one year ago, I noticed that the scrolling was a bit jittery while I touched the screen. Any scrolling that happened when I wasn't touching the screen was smooth so I figured it had to do with the digitizer. I read some thread about it but never found a solution, and I finally accepted the fact that this phone didn't feel as smooth as my Nexus 6 did on this regard.
However, after the Android Pie update, the scrolling is now much smoother. There's barely any noticeable difference between scrolling with my finger in Chrome and scrolling that happens without interaction (like when I push away a page and let it scroll by itself).
Am I the only one experiencing this? Maybe I'm extra sensitive to these things, or perhaps my phone had some weird bug that finally got overwritten with the OS update - I never tried factory resetting my device.

Screen Flickering

Hi,
So I offer this phone to my wife this xmas and everything was going smooth until we found this issue:
https://www.youtube.com/watch?v=xYFdyDwuS_w
The bottom screen does this flickering when typing with Swiftkey keyboard on some apps. This one is Doggcatcher but it happens on other apps too.
If I swap to GBoard it does not happen. We're on Android Pie 9.0.
Has anyone found this issue?
Seems like a graphic bug in that specific keyboard.
Please, i need help.
Evaluate for yourself whether it is related to this topic.
Occasionally, graphical glitches appear on my Mi A2 lite, (4/64, Android Pie, December update, locked bootloader, no root, intact system).
In most cases, they flickering all over the screen, and in some other cases they are frozen, as is shown in attachment.
They are completely random and they appear through many applications that i use.
I can not determine the cause.
Does anyone else have a similar problem?
me... on chrome and all app that use webview... during call status bar is flickering... when switch to the camera in whatsapp with swipe to set status... and other
Something similar here, if Facebook Messenger chat head is overlaying YouTube it flickers a lot (only the actual video but the description and recommend are always working without flicker also no problems in fullscreen), less often it happens with Chrome and sometimes YouTube does it without Facebook Messenger even being open (Android Pie Dec. 5) [also it didn't happen for the first few weeks with 8.1 then Pie got released and worked well for some days then this started to happen]
I have that problem , the notification bar flickers a lot and when on video calls, it shows a black flickering rectangle at the bottom of the screen
Hi, I've got the same problem here. For me, the flickering appears when the keyboard is open, and get faster while typing, please does someone know how to fix that?

It is true that it is the keyboard, my keyboard developer is fixing the bug making it do that as we speak but in my case the whole screen flashes black instead of the little box you have
The problem with the flickering screen in some apps like Youtube, Chrome or Instagram can be fixed as follows:
Go to Developer Options and activate "disable hw overlays"
However, the setting must be set again after every Phone restart.

Isn't that bad long term?
"Without a hardware overlay every application that is displaying things on the screen will share video memory and will have to constantly check for collision and clipping to render a proper image, this can cost a lot of processing power. With a hardware overlay each application gets its own portion of video memory, getting rid of the need to check for collision and clipping."
