Bug 371686

Application: kwin_x11 (5.8.2)

Qt Version: 5.7.0
Frameworks Version: 5.27.0
Operating System: Linux 4.4.21-1-lts-ck x86_64
Distribution (Platform): Archlinux Packages

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

I opened Chromium and the desktop froze for a moment, and then a message appeared saying that KWin had crashed. I was able to reproduce this again once by closing and reopening Chromium, but not again after that.

The crash can be reproduced sometimes.

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