Application: kwin_x11 (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-21-generic x86_64
Distribution: Ubuntu 15.04

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

Any time I play CS:GO kwin either crashes early on or specifically during the second match. I've messed with the settings of kwin_x11 and CSGO and gone through everything I can think of, and kwin always crashes

The crash can be reproduced every time.

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