Screen recording of the bug happening twice in a row
SUMMARY
Most of the time when I try to view the system tray's hidden icons using the
arrow symbol in my panel, it does not actually render a popup, making all
hidden symbols inaccessible. Only at the very start of a new session does it
actually work as intended, or if I kill and restart plasmashell via terminal.
STEPS TO REPRODUCE
1. Click the "Show hidden icons" up arrow in the task bar to open the popup
2. Click the "Close popup" down arrow in the task bar to close it again
3. Repeat 1+2 quickly until the popup does not show up anymore
OBSERVED RESULT
- The popup showing my hidden system tray icons does not appear
- Besides the actual popup, the state is still correct from a tray perspective:
the arrow icon points downwards, the tooltip updates to "Close popup", a blue
bar renders on top of my system tray icons
EXPECTED RESULT
- Popup with hidden system tray icons does render and state is correct

ADDITIONAL INFORMATION
I do not know the exact trigger which breaks the rendering of this popup. I
also could not find any relevant logs in journalctl, but it happens with most
of my regular desktop activities after some time and is quite annoying.
Basically whenever I do want to expand the tray, there's a ~90% chance that it
already broke in my session so far (gaming, browsing, chatting, voice calls,
etc.).
I have tried to find some steps to reproduce more reliably, which are the ones
I added to "Steps to reproduce", but these are not the only way to trigger this
problem. It still seems to happen a bit randomly, sometimes sooner, sometimes
later. I even recorded it happening twice in a row within a minute to show that
this happens regularly, see the attached video. Right before I started
recording, it broke on the 2nd time opening the popup. Then it took me 20
seconds of closing and opening during the recording, the next time 5 seconds
during the recording.
This bug has been happening to me for quite some time, I do not think it's
specific to only my current version. I believe it's been present since the
beginning when I started using KDE on my work laptop (~May 2025) although I
don't know for sure. I've noticed it a lot more recently on my personal PC when
I started using Arch and KDE. My work laptop is using a derivative of Debian
testing, so it's likely not only the current latest version that is affected,
although I do not know exactly since when.
I can reproduce it even without any open windows and it also doesn't seem to
matter which icons I have visible in the tray or not. It also doesn't seem to
matter whether I'm using 1 (ultrawide 32:9) or 2 (16:9) external monitors or
just an internal laptop monitor.
I am using Wayland and my panel is configured as follows, not sure if it
matters: Position bottom, Alignment center, Width "Fit content", Always
visible, Opacity Adaptive, floating panel and applets, height 44.
