SUMMARY
Kwin crashes when opening games that try to disable the compositor, it causes
the windows to flicker and continuously alt tab to desktop until it completely
crashes and no windows can be moved or closed I have to restart the pc to fix
this issue, disabling Allow applications to block compositing seems to help but
it still happens on game start up.
STEPS TO REPRODUCE
1. Login into plasma x11
2. Open a game that tries to disable composition e.g Minecraft or cs2
OBSERVED RESULT
Windows flicker and continuously alt+ tab to the desktop and back to the game
over and over, until the desktop "freezes", images still render, videos and
games still move but no mouse or keyboard action trigger any type of response
on opened windows.
EXPECTED RESULT
game runs without crashing kwin.
