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.
