Bug ID: 512079
Summary: Plasmashell hang with high RAM usage when using
"Search"
Classification: Plasma
Product: plasmashell
Version First 6.5.2
Reported In:
Platform: EndeavourOS
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: Global Menu widget
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Target Milestone: 1.0
SUMMARY
Using the "Search" button's functionality after adding the global menu for the
first time, plasmashell got hanged, with ~10.2 GB total RAM usage (increased
over the period while unresponsive).
Used it with Konsole (konsole 25.08.3) in focus.
STEPS TO REPRODUCE - Not sure if reproducible
1. Add Global Menu to Default Panel using "Add or Manage Widgets" (for the
first time??)
2. Open a Konsole window
3. Click the search button in the Global Menu and type some stuff in the search
bar
4. Wait
5. systemctl --user restart plasma-plasmashell
OBSERVED RESULT
On step 4:
- All panels hanged and panel-related shortcuts stopped working
- The popped-up search bar stayed visible
- Clicks on the 'icons and text task manager' were unresponsive
- According to Plasma System Monitor, the RAM usage of plasmashell gradually
increased upto ~10.2 GB. Swap usage was still at 0
- Alt+Tab was working, but without the overlay
- mouse cursor was working
- the konsole window, for which the global menu had opened, was responding
properly
EXPECTED RESULT
- plasmashell does not become unresponsive
- plasmashell does not start using high amount of memory
- search results come up
