Description Balpo 2016-10-10 23:27:43 UTC
Application: kwin_x11 (5.8.0)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.7.0-1-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
- What I was doing when the application crashed:
opened a new window
- Unusual behavior I noticed:
screen flickers, the cause seems to be tooltips or some sudden drawing
- Custom settings of the application:
none important

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