Description billrclarity 2017-03-28 23:57:39 UTC

Application: kwin_x11 (5.8.6)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.4.49-16-default x86_64
Distribution: "openSUSE Leap 42.2"

-- Information about the crash:
KWIN crashes at random intervals for no obvious reasons except that I click somewhere on the screen, usually to close or select a window.  The screen blinks and an error window pops up which allows me to provide info.  Sometimes, KWIN will lock up after the crash, and I have to go to the psudeo terminals to reboot.  At other times, I may not even be able to get to the psudo terminals and have to manually power off the system.  After one of these crashes, one or more of the open windows may have it's title bar above the level of the screen, so it can't be moved.  I am seriously thinking of switching to gnome.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault

Unfortunately the backtrace is lacking debug symbols. If you are able to reproduce please install the debug packages provided by your distribution (please ask the distribution support channel on how to install them) and attach a new backtrace.
