            Bug ID: 350872
           Summary: K-win crash when exiting steam games
           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: genmavlad at gmail.com

Application: kwin_x11 (5.3.1)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-25-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
I was exiting a game on Steam ("J.U.L.I.A. Among the Stars" this time), when
kwin crashed. This happens, but not regularly (I'd say 2 out of 5 times when
exiting a game launched from Steam), and not consistantly with any particular
games.

The crash can be reproduced sometimes.

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