Description Andreas Hartmann 2016-12-18 04:26:42 UTC

Application: kwin_x11 (5.8.3)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.4.38-1-desktop x86_64
Distribution: "openSUSE Leap 42.2"

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

I did nothing particular. But I can see it most of the time at the beginning of a session. Afterwards it is working mostly for longer time. But comes up again. There are two more crashes from yesterday.

Maybe, it is related to starting new programms? I could see it while starting the process list (CTRL-ESC) or Firefox, e.g.. But this is just an assumption.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

As a workaround use the breeze window decoration.
