SUMMARY
When using 555.[42.02, 52.02] drivers and floating auto-hide panels, Plasma Wayland is basically broken.

STEPS TO REPRODUCE
1. With an NVIDIA GPU, get 555 driver.
2. Get KDE beta 6.1 or build master branch with kdesrc-build.
3. Log into Wayland session.
4. Make a panel or two hide-under-windows in panels' settings.

OBSERVED RESULT
Sometimes (consistently), when clicking on the panel to open up windows, they open only after moving the cursor onto the other auto-hide panel.
When pressing the volume change button, notifications (consistently) often don't show up or get frozen (not hiding after some time), which, again, can be temporarily un-broken by moving cursor onto the other panel. 
Also some other stuff that i am not able to describe.

EXPECTED RESULT
Everything working fine, as it was on 550 driver (on the same Plasma version!), or in X11 session.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Fedora 41 (rawhide), also Arch Linux
(available in About System)
KDE Plasma Version: 6.1.80 (kdesrc-build) AND beta 6.1 from Fedora's packages
KDE Frameworks Version: 6.4.0
Qt Version: 6.7.1

ADDITIONAL INFORMATION
nvidia-drm.modeset=1, nvidia-drm.fbdev=1, nvidia.NVreg_EnableGpuFirmware both 0 and 1

If upgrading the NVIDIA driver caused this, then the issue is clearly caused by the new version of the NVIDIA driver. I'd recommend contacting NVIDIA about it. You paid money for their hardware, so you're entitled to support for it!

So please report this issue to the NVIDIA folks, either by sending an email to linux-bugs@nvidia.com or making a post at https://forums.developer.nvidia.com/c/gpu-graphics/linux. It would be helpful to the NVIDIA developers if you could run nvidia-bug-report.sh and attach the resulting file in your report. Thanks!
