Bug 487075

I'm also experiencing this on KDE 6.1.3. I don't have a good way to reproduce it yet unfortunately, but so far it has always happened while hovering the mouse above the icons in the system tray like the volume, notifications, etc. After this the panel will freeze completely, and I also can't right click on the desktop background. The last tooltip that was shown when hovering above the icon that caused it to freeze remains in place.

Software/Hardware info:
Operating System: Arch Linux 
KDE Plasma Version: 6.1.3
KDE Frameworks Version: 6.4.0
Qt Version: 6.7.2
Kernel Version: 6.9.8-zen3-xanmod1-1 (64-bit)
Graphics Platform: Wayland
Graphics Processor: NVIDIA GeForce RTX 4070/PCIe/SSE2

Does it happen on Wayland as well, or only on X11?

I'm experiencing it on Wayland yes. I haven't tried it on X11 myself because ironically (given the historical Nvidia issues with Wayland) I can't get an X11 session running on this machine anymore/at the moment.

Experiencing same bug. Found a reliable way to reproduce it: 
Hover on taskbar icon -> Hover on taskbar window thumbnail -> Move cursor from thumbnail -> Freeze
Clicking on thumbnail, clicking too fast, modifying items on panel, changing themes also freezes panel.
No errors or warnings when freeze happens. Process needs to be killed.

Are you able to confirm that way of reproducing the issue, bugreporting@mailna.me? I can't.

Not the one you asked but I also can't reproduce it with those steps. I do still however have it happen quite quickly by just playing around with the icons in the system tray. Especially if I hover the cursor above the icons long enough to produce a tooltip popup to display, then moving the cursor between icons and randomly clicking some of them etc.

It's likely that there are multiple issues producing the same result of a frozen panel here that people are experiencing.
