Application: kwin_x11 (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-16-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
Was viewing Weather Underground Wundermap's radar, playing the animation worked fine. After zooming in a couple times, it crashed. Chromium stayed open and working fine, as did the map. I was still able to interact with the map fine after the KDE interface restarted.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
