Summary: Plasma crash when dual screens turned off
Product: plasmashell
Version: 5.19.5
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: kdeb...@knick-knack.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.19.5)
Qt Version: 5.14.2

Operating System: Linux 5.8.0-36-generic x86_64
Windowing system: X11

-- Information about the crash:
- What I was doing when the application crashed:
Dual monitors - when the screens have the power switched off (using the power
button on the front of the monitor) and I turn them back on after some amount
of time, plasmashell has crashed. The primary monitor displays large grey
macroblocks and nothing else. Cycling the monitor power via the front button
will resolve this, however I manually need to restart plasmashell from the
alt-f2 menu
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
