Mockup of observed result

SUMMARY

When initially opening the menu, the bottom portion with Applications, Places, Sleep, Restart, Shutdown, and Leave... items renders black for about half a second. The rest of the menu is not affected. I was not able to screen capture this happening so I have attached a mock up using an edited screenshot of the normal behavior.

STEPS TO REPRODUCE
1. Click the icon to open the menu

OBSERVED RESULT
A black "flash" near the bottom of the menu

EXPECTED RESULT
Normal menu opening animation

Reproduced in 5.22.4
Comment 2 Nate Graham 2021-08-05 00:58:00 UTC 
Should be fixed in Plasma 5.23 with the recent code rewrite. If not, then it's an NVIDIA driver bug, and you should report it 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-unix-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!
