SUMMARY
When i am using Nvidia GPU with proprietary drivers and i am on Wayland
session, the Application Dashboard has visual glitches when moving cursor on
the blurred background (you can check attached video file). This glitch in some
cases is less intensive. Foe example if i have fullscreen webbrowser opened and
playing some YT video and i open Application Dashboard, this glitch shows up
only very close to the mouse cursor and does not leave this track as shown on
the video.
STEPS TO REPRODUCE
1. Use PC with Nvidia GPU and proprietary drivers
2. Login with Wayland session
3. Open Application Dashboard (when blur effect is active in system)
4. Move mouse cursor around - you should see the glitches
OBSERVED RESULT
Moving cursor over Application Dashboard blurred bckground renders glitches -
leavs strange darker track after cursor.
EXPECTED RESULT
Moving mouse when Application Dashboard is opened (fullscreen) should not
render any glitches.
