Bug ID: 428763
Summary: Activities Break when switching and screens flicker,
KDE system Settings Activitues under workspace
behavior crashes system settings.
Product: systemsettings
Version: 5.19.5
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: trwid...@gmail.com
Target Milestone: ---
Application: systemsettings5 (5.19.5)
Qt Version: 5.15.1
Frameworks Version: 5.73.0
Operating System: Linux 5.8.17-300.fc33.x86_64 x86_64
Windowing system: Wayland
Distribution: Fedora 33 (KDE Plasma)
-- Information about the crash:
- What I was doing when the application crashed:
When you got to system settings, Workspace behavior and Activities the left
panel becomes black and all selection goes away for the menu, and the rest of
the appication stops responding. Then crashes if you click around anywhere in
the app, I have repeated this process 3 times.
When you also try to switch activities, it looks like the old activite is
behind the new one, and the screen starts flickering. Best way to describe this
is you have double vision and are seeing two activities stack on top of one
another, then the screen starts flickering like a old high speed shutter
film... Its kind of a neat effect but not good If you are tying to work. :)
When you switch back to the first activie the problem goes away and when you
switch too the second, the flickering and double image happens again. If i log
out when in the second activitie the system reboots, and does not go to a
logout screen. I upgraded from fedora 32 to 33 and all packages are up do date.
The crash can be reproduced every time.
