[Android] App has a black screen after being left in background

[zambetpentru]

Steps to reproduce

It appears you need Android 14 (e.g Samsung S22 Ultra), can not appear to repeat on Android 12. Haven't checked recently but probably okay on Android 13 as well... Have never seen on issue on iOS.

Have been able to repeat it with our Apps on stable 3.19.3 (and prior versions in 3.x) and the latest Google Earth and Wonderous apps.

1. Open your Flutter App
2. Change to another app or two
3. Turn off screen
4. Leave for 5 minutes
5. Turn on screen and try to select the App

Expected results

App should show as normal and not as a Black screen. When you select the App twice it will open.

Actual results

Screen is blank, until I select the App twice. Also can see flicker sometimes when looking at the list of open Apps.

Code sample

This should be a simple repo: #143992
