Bug ID: 469175
Summary: Panel with taskbar freezes visually but remains
operational
Classification: Plasma
Product: plasmashell
Version: 5.27.4
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Panel
Assignee: plasma-b...@kde.org
Reporter: dcalv...@gmail.com
CC: niccolo.venera...@gmail.com
Target Milestone: 1.0
SUMMARY
Default panel with taskbar and clock freezes visually at some point during
operation.
The panel can still be interacted with but it won't update any information, the
time on the digital clock remains as it was when it stopped working, and
taskbar icons that would update some information (such as the new email counter
within the kmail icon) will not update.
STEPS TO REPRODUCE
1. Boot and login normally.
2. Use the system normally and at some point some panel will stop responding,
normally the main display one, but not exclusively.
OBSERVED RESULT
Panel stops visually updating, and becomes "frozen", but interaction is still
possible, so I'd call it "functional".
EXPECTED RESULT
Panel doesn't freeze visually at all.

ADDITIONAL INFORMATION
It can be brought back to a working state by right clicking the panel, entering
edit mode and changing some visual aspect of it, such as the height.
It does not happen on all panels simultaneously, it seems to affect a single
display, though not necessarily the same one every time.
It may have happened around the time I opened a game running with Proton, but
unsure at this point.
Even more strange, during the "frozen" period, if one clicks on the pinned
taskbar icon for "System Settings" it opens some windows that existed at some
point on a different activity.
Even stranger is the fact that this activity no longer exists as I deleted it
from the activities menu, but during this issue, clicking on this icon brings
back the apps that I had open back then, which were a browser and a konsole
window.
This strange behavior ceases when the workaround of changing the panels height
is applied.
