Bug ID: 512305
Summary: Plasmashell consumes all available RAM when I click on
notifications icon
Classification: Plasma
Product: plasmashell
Version First 6.5.3
Reported In:
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Notifications
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Target Milestone: 1.0
SUMMARY
I upgraded to KDE Plasma 6.5.3 and launched a new Plasma Wayland session via
GDM (login manager). I was looking for a setting to disable the OSD
notifications when I noticed that the CPU fan was getting louder, so I checked
what was going on and found that something was eating my RAM. I managed to
reboot the computer by pressing CTRL+ALT+DEL, launched a Plasma Wayland session
and investigated what could have caused the memory usage spike. When I clicked
on the notifications icon in the systray, I noticed that the CPU fan was
getting louder again and I checked that the RAM consumption was increasing, so
I concluded that the notifications widget caused the RAM usage spike. There
weren't any notifications listed by the way.
STEPS TO REPRODUCE
1. Upgrade to Plasma 6.5.3 (I upgraded from 6.5.2)
2. Launch new Plasma Wayland session (I didn't test the X11 session)
3. Click on notifications icon in systray (the bell)
OBSERVED RESULT
Plasmashell starts to consume more and more RAM (in my case it reached 61,7 GiB
according to the journal) and (I believe) the panel becomes unresponsive.
CTRL+ALT+DEL still works if I press it immediately so I can reboot via the
lockscreen (or whatever it is called).
EXPECTED RESULT
Plasmashell should not eat my RAM. ;-)
