Sentry Crash Report:

Description Levi Self 2015-06-18 22:59:15 UTC 
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

Comment 1 Levi Self 2015-06-18 23:03:38 UTC 
I can get another backtrace if needed, I'm not sure that one is useful as I did not have the debugging symbols until I made it.
Comment 2 Levi Self 2015-06-19 02:47:39 UTC 
Another detail, disabling the compositor stops crashing.
Comment 3 Levi Self 2015-06-21 04:33:45 UTC 
Fixed product and version
Comment 4 Thomas Lübking 2015-12-14 18:31:17 UTC 
fglrx bug, disable blur cache results (run "kcmshell5 kwineffects", filter for blur, click the config button - it's the only checkbox)
If it still crashes, disable blurring and problably the "contrast" effect as well.

Alternatively, consider using the radeon driver.

Sorry for the delay.
Fyi, you changed the assignment of the bug to "unassigned-bugs@kde.org" - I found it by pure luck.
Be careful about the field unless you know what you do.
