Application: kwin_x11 (5.11.3)

Qt Version: 5.9.2
Frameworks Version: 5.40.0
Operating System: Linux 4.13.12-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
Switching browsers windows and selecting the one I want to appear fullscreen
- Unusual behavior I noticed:
Annimations are becoming laggy short before the crash (like the hover animation when the mouse is over a window)

The crash can be reproduced sometimes.

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