Bug ID: 424543
Summary: Plasma crashes when a widget is moved to a different
screen and its background is toggled
Product: plasmashell
Version: 5.19.3
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: ste.pigo...@gmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.19.3)
Qt Version: 5.15.0
Frameworks Version: 5.72.0
Operating System: Linux 5.7.9-arch1-1 x86_64
Windowing system: X11
Distribution: "Arch Linux"
-- Information about the crash:
- What I was doing when the application crashed:
I was moving a widget from my primary screen to my secondary screen, when I
noticed the letters on the widget were getting scrambled.
Then, I clicked on the Show Background button of the widget, and Plasma
suddenly crashed.
- Unusual behavior I noticed:
The scrambled letters on the widget.
- Custom settings of the application:
I tried with both the Network Speed graph, the CPU Usage graph, and both gave
me the same problem.
- Extra:
I just tried to reproduce the bug and make a screenshot to attach to the
report, but as soon as I pressed PrintScr to take the screenshot, Plasma froze
and stopped drawing the screen, leaving the KDE Crash Handler as the only
usable application.
The crash can be reproduced every time.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
