Application: kwin_x11 (5.8.6)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.4.57-18.3-default x86_64
Distribution: "openSUSE Leap 42.2"

-- Information about the crash:
- What I was doing when the application crashed:
Logging in. Sometime early in the startup of the KDE environment Kwin report that it has crashed. I get a dialogue with the option to restart which I usually do, even though it seem to have done so by itself by that time.
This happens often but no always.

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