Created attachment 127038 [details] Stacktrace SUMMARY KWin indeterminately crashes when changing the QStyle under Wayland [git master as of commit 745981f] STEPS TO REPRODUCE 1. Change QStyle 2. If it doesn't crash, try again OBSERVED RESULT KWin crashes changing QStyle EXPECTED RESULT KWin doesn't crash when changing QStyle
Errata: KDecoration, not QStyle
This looks like a driver bug. ::cleanup() destroys egl surfaces (if any) and the opengl context. I don't think there's any crashy.
