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".
