            Bug ID: 398114
           Summary: KWin crash when starting games
           Product: kwin
           Version: 5.13.4
          Platform: Archlinux Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kwin-bugs-null@kde.org
          Reporter: joewinzer@googlemail.com
  Target Milestone: ---

Application: kwin_x11 (5.13.4)

Qt Version: 5.11.1
Frameworks Version: 5.49.0
Operating System: Linux 4.18.5-arch1-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

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

Once I started the application the screen turned black for a few times before
the application window was shown.
In dual screen setup or just the laptop screen, the behavior is the same.
This bug doesn't interfere with any functionality but it's just annoying.
I tried it on other DE (lxqt, xfce) and there the compositor doesn't crash or
any other visual artifacts.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KWin (kwin_x11), signal: Aborted
Using host libthread_db library "/usr/lib/libthread_db.so.1".
