Application: kwin_x11 (5.12.8) Qt Version: 5.9.4 Frameworks Version: 5.45.0 Operating System: Linux 4.12.14-lp150.12.61-default x86_64 Distribution (Platform): openSUSE RPMs -- Information about the crash: - What I was doing when the application crashed: I was just running kwrite as root user and just resizing the kwrite window area when kwin crashed. - Unusual behavior I noticed: When I was re-sizing kwrite the screen went blank for a second, then displayed virtual screen #23, blanked again for a second and the kwrite window moved up making it's toolbar go off the top of the screen. The crash can be reproduced sometimes. -- Backtrace: Application: KWin (kwin_x11), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".
