Bug ID: 497903
Summary: plasmashell locks up with 100% CPU after adding
widgets to panel with Audio Volume widget or Battery
and Brightness widget on it
Classification: Plasma
Product: plasmashell
Version: 6.2.4
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: Audio Volume widget
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Target Milestone: 1.0
SUMMARY
After adding an instance of the Audio Volume widget or the Battery and
Brightness to a panel, adding further widgets to that panel cause plasmashell
to lock up and run at 100% CPU until killed. Other widgets may cause the same
issue.
STEPS TO REPRODUCE
1. Create a new empty panel (location does not matter, set Width/Height to 'Fit
Content', Visibility to 'Dodge Windows')
2. Add an Audio Volume or Battery and Brightness widget to the panel
3. (note system is still functional)
4. Add any other widget (e.g. Digital Clock) to the same panel
5. Plasma UI locks-up, can still Alt-Tab to applications but panel editing is
frozen
6. Running 'killall -9 plasmashell' recovers system but latest edits are lost
OBSERVED RESULT
1. Plasmashell locks up, no further editing of panel configuration is allowed
2. Alt-tab can still be used to switch applications (which still function)
3. Ctrl-Alt-F3 can be used to switch to a text-only console which can be used
to kill plasmashell to recover the system
EXPECTED RESULT
The second widget should be added to the panel and editing is allowed to
continue.
