SUMMARY After some amount of time, the panel just freeze but all the buttons and tooltips work properly. STEPS TO REPRODUCE 1. Log-in to a Plasma Wayland Session with NVIDIA GPU. 2. Use your computer for an hour or two. 3. Eventually the panel will freeze. OBSERVED RESULT The panel will freeze eventually at some point, but all the panel functions continue to work. plasmashell --replace fixes this issue. EXPECTED RESULT The panel should continue to respond and update normally without any freezes. SOFTWARE/OS VERSIONS Linux Kernel: 5.16.1-arch1-1 KDE Plasma Version: 5.23.90 KDE Frameworks Version: 5.90.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION NVIDIA GeForce GTX 1060 6GB NVIDIA Proprietary Driver 495.46 Latest packages - all up-to-date, unstable Plasma 5.23.90 and latest qt5-wayland with merged NVIDIA GBM fix.

Oh my goodness. Not sure if this is a Plasma bug or a KWin bug or an NVIDIA driver bug. May be a combination of all three
(In reply to Nate Graham from comment #2) > Not sure if this is a Plasma bug or a KWin bug or an NVIDIA driver bug. May Atleast its not as bad as it was previously. So should I report this to NVIDIA too or should I wait for confirmation that this is a NVIDIA Bug? I also noticed that once when I did `plasmashell --replace`, there was a crash when panel was replaced and the panel just froze as soon as it appeared, maybe this crash is the reason? Another time, when I did this, the panel appeared, disappeared and then reappeared (but it worked normally, just weird replace behavior).
( No Backtraces because no debug symbols in Arch :( )
Oh, that might be it, yeah. Even if the backtrace is crappy and lacking symbols, it's better than nothing, and we might be able to see if it's the same as something else.
Created attachment 145789 [details] Part of the output of `journalctl -xe` when the crash occured. I am now submitting the journalctl -xe output when I did plasmashell --replace and it crashed.

FYI: There is an nVidia/Wayland specific issue with identical symptoms to this, which https://codereview.qt-project.org/c/qt/qtwayland/+/393273 alone doesn't fix. It seems to be due to a bug in libnvidia-egl-wayland: https://github.com/NVIDIA/egl-wayland/issues/52 I can't reproduce the issue with this patch, but can without it: https://github.com/NVIDIA/egl-wayland/pull/53
Confirmed I have the same exact issue. The Panel will no longer refresh but you can hover with tooltips around the panel and see that there is still interactivity and operability is there, the visual is not in sync with the status of the panel.
