Visual bug when showing all open windows

Small visual bug when showing all programs opened by the "Windows" shortcut, as you move the mouse, these small artifacts appear.

I switched to Zorin ~1 month ago, and I've always had this little bug.

That looks like the Windows Switcher. Can you please clarify the bug so we know what to look for? I may have not seen it since I was not sure what I was supposed to see.

1 - Have at least 2 programs open.
2 - Click on the "Windows" button.
3 - Move the mouse between programs, usually on the lower right side of the screen an artifact is showing. Occasionally the lower left side will also show artifacts.

Note: I tried recording a native video, but it doesn't replicate the problem.



When the recording does not show the artifact, but the screen does, this points toward Graphics issues.
What is your terminal output of

sudo lshw -C video

?

For the 1060, I would test the 470 driver with 525 being the latest. The Nvidia 535 driver was buggy on new and old hardware alike.

I understand, I'll try to change to the 525 and then I'll give you feedback.

Switch to version 525 and 470, the problem persists.
