SUMMARY *** With the frequency once a day, panel frezes completely. Absolutely nothing on the panel is clickable, so it looks like a dummy screenshot, not an active element of DE. *** STEPS TO REPRODUCE 1. Settings: default, except "classic task manager" and Layout: Desktop 2. Use the system normally OBSERVED RESULTS (2x) 1.Once a day panel freezes completely. Noting is clickable, i.e. panel becomes dummy. Krunner works to launch Konsole. 2.Shutdown as "su -" hangs on "Modem manager is shut down": $ shutdnow now System cannot be shut down after panel freezes completely. EXPECTED RESULT Panel not to freeze to take down the whole KDE. Did not occur prior versison 6.0.4 (regression). This bug is critical as it freezes KDE, so as a result system cannot be shutdown by a normal user leading to hard reset and data loss (applications cannot be switched, work cannot be saved, disk is shudown while mounted and running, possible writing something leading to disk errorrs and data loss, hence marked as CRITICAL. REASON OF TOTAL PANEL FREEZE: Impossible to diagnose by the user. SOFTWARE/OS VERSIONS KDE Plasma Version: 6.0.4 KDE Frameworks Version: 6.1.0 Qt Version: 6.7.0 Graphics Platform: X11 Graphics Processor: Mesa Intel HD P.S. This is the worst bug on KDE 6, so far. Whatever happened on 6.0.4, must be reverted (regression). For me its a total showstopper :(
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.
(In reply to Nate Graham from comment #6) > 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.
So all of you with NVIDIA GPUs, you're experiencing something different from what the OP is reporting; it's an NVIDIA GPU driver bug, especially if you're using the experimental 555 driver series. bugreporting@mailna.me, are you still able to experience this in Plasma 6.1.4 or later? If so, I'll see if I can walk you through some troubleshooting.
