            Bug ID: 354611
           Summary: KWin crash with screen corruption
           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: joao.eiras at gmail.com

Application: kwin_x11 (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-31-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
When I boot my pc from sleep or switch from a terminal to my desktop, sometimes
the screen is corrupted (see attached screenshot). I think this has to do with
using a very novel nvidia driver so I can work with CUDA. Anyway, after booting
from sleep, if the screen is corrupted, I'll switch back and forth between a
terminal and the desktop environement until the corruption goes away. After
taht I just input my password in the login dialog and log into KDE. KWin
usually crashes then. I don't know if the crash has anything to do with the
screen corruption, but I wouldn't be surprised.

The crash can be reproduced sometimes.

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