I play Zenless Zone Zero which is very taxing on the processor (CPU/GPU constantly at 90℅) and if I just take a screenshot and click the editor, it closes the game.
I can’t change nothing x settings (no lag mode on CMF needs to be turned on again if you disconnect) or reply to a message unless in popup view. Putting the game itself in popup while switching works for a minute, but if I don’t maximise it quickly it again closes.
Battery optimisation is set to unrestricted and game mode’s “performance mode” is turned on. The OS never kills my other apps running permanently in background, and they have those same settings.
