Today's screenshot. Top line affected.

STEPS TO REPRODUCE
1. Hover over any of the taskbar icons (Application Launcher, clock, tray icons, running application etc)  
2. 
3. 

OBSERVED RESULT
Some of the tooltip text is distorted as in screenshot1. It is always the text on the first row, in the bigger font that is affected.

This is unfortunately an NVIDIA graphics driver bug. 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!

> Please report this issue to the NVIDIA folks

I would but I very much doubt anyone will want to fix a bug in 14 years old hardware. They will probably say I can get a complete more modern system for 50€ on ebay. Thanks anyway.

You're probably right! 😅
