It's an NVIDIA GPU driver issue. :( Some of it was fixable in Qt 6.9; see Bug 480800. The rest needs to be fixed by NVIDIA.

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!
