Screen Flickering

[gonsa]

Hi,

So I offer this phone to my wife this xmas and everything was going smooth until we found this issue:

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?

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]

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."

So far, I have not encountered any problems because of this.
