Platform: openSUSE RPMs
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: billrclar...@stny.rr.com
Target Milestone: ---
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

-- Information about the crash:
- What I was doing when the application crashed:
Just made the winning move in Freecell. Frequent but unpredictable crashes
when clicking on KWIN. No consistancy observed when it happens.
The crash can be reproduced sometimes.
