            Bug ID: 346024
           Summary: Kwin Crashes after suspend
           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: chadwick.ferguson at gmail.com

Application: kwin_x11 (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-12-lowlatency x86_64
Distribution: Ubuntu Vivid Vervet (development branch)

-- Information about the crash:
- What I was doing when the application crashed:

Kmenu > Leave > Suspend

- Unusual behavior I noticed:

Kwin crashes, sometimes complete graphical distortion/SDDM not shown

- Custom settings of the application:

Nvidia Xorg http://ppa.launchpad.net/xorg-edgers/ppa/ubuntu
other ppa's have nothing to do with QT/Kwin

The crash can be reproduced every time.

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