            Bug ID: 389733
           Summary: Plasma (maybe Mesa?) crashes randomly during Youtube
                    playback
           Product: plasmashell
           Version: 5.11.5
          Platform: Neon Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kde@davidedmundson.co.uk
          Reporter: rhodichelicoid@aol.com
                CC: plasma-bugs@kde.org
  Target Milestone: 1.0

Application: plasmashell (5.11.5)

Qt Version: 5.9.3
Frameworks Version: 5.42.0
Operating System: Linux 4.13.0-32-generic x86_64
Distribution: KDE neon User Edition 5.11

-- Information about the crash:
- What I was doing when the application crashed:
Watching a Youtube video through Chromium, fullscreen.

- Unusual behavior I noticed:
Randomly (infrequent, this is the second time in a few weeks) during
full-screen Youtube playback, video stops, audio continues, screen flashes
multiple times, and after about 2-3 seconds of this behavior, video recovers
and Plasma informs me it had crashed.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Bus error
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
