-- Information about the crash:
- What I was doing when the application crashed:
From steam, ran  Killing Floor 2 as the game opened i got 2 Dr Konqui notifications about kwin's crash.
To be more precise as the game went fullscreen and the compositor turned off kwin crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
