Artifacts on blurred surfaces with nVidia on Wayland
SUMMARY
With enabled blur effect and when ever the cursor moves across a blurred
surface it leaves squared trails of it's path.
As soon as the blurred component receives a full redraw the blur gets normal
again.
Like moving the window or hovering an item in the start menu.
STEPS TO REPRODUCE
1. Run Plasma in Wayland mode on nVidia
2. Move cursor across any blurred surface
3. Artifacts remain till the next full redraw.
OBSERVED RESULT
Artifacts left on blurred surfaces
EXPECTED RESULT
No artifacts on blurred surfaces as with X11
