            Bug ID: 347483
           Summary: Crash of system settings (Systemeinstellungen) after
                    graphics pane
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: bug at christianmayer.de

Application: systemsettings5 (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-16-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
I had the graphics pane open and switched away from it. The crash is even
happening when I didn't change any setting...

- Unusual behavior I noticed:
I get slight artifacts on the screen during system interaction like moving the
mouse cursor over a list where the current line gets highlighted. Or during
some (menu) animation.
The artifact are shadows on the top part of the screen. 
When the animation is stoped no artifacts are remaining.

The crash can be reproduced every time.

-- Backtrace:
Application: Systemeinstellungen (systemsettings5), signal: Segmentation fault
