Description Vlad Zahorodnii 2020-10-22 07:55:06 UTC 
SUMMARY
In some cases, kwin has to restart compositing. One such case is where user settings have changed. Another one is where a graphics reset has occurred.

STEPS TO REPRODUCE
1. Change any settings in Compositor KCM, e.g. "Rendering backend"

OBSERVED RESULT
The screen turns black

EXPECTED RESULT
The EGLDevice backend is properly restarted
