Bug ID: 447678
Summary: "plasmashell" is froze and began 100% 1 core cpu usage
and unlimited memory consumption when opening the
"Notifications" applet
Product: plasmashell
Version: 5.23.4
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: critical
Priority: NOR
Component: Notifications
Assignee: k...@privat.broulik.de
Reporter: timoha9...@mail.ru
CC: plasma-b...@kde.org
Target Milestone: 1.0
SUMMARY
"plasmashell" is froze and began 100% 1 core cpu usage and unlimited memory
consumption when opening the "Notifications" applet.
STEPS TO REPRODUCE
1. A notification came to my computer via "KDE Connect" from my smartphone
2. I clicked on the "Notifications" button (Bell icon) in the system tray
OBSERVED RESULT
... and at this moment all the plasma elements (taskbar, system tray,
application menu, clock) froze and did not react to any actions. The
"Notifications" window did not appear. In the system monitor, I found that the
"plasmashell" process began to load 1 CPU core by 100% and a large consumption
of RAM and swap (memory leak).
EXPECTED RESULT
Displaying the "Notifications" applet.

stopped and all plasma elements began to function normally.
