Application: kwin_x11 (5.5.5)

Qt Version: 5.6.0
Operating System: Linux 4.4.6-301.fc23.x86_64 x86_64
Distribution: "Fedora release 23 (Twenty Three)"

-- Information about the crash:
- What I was doing when the application crashed:

launching a full screen game crashes kwin. My resolution in the game is usualy set to native but the videos that play before the game menus are usualy in a different resolution

The crash can be reproduced every time.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
