Unity desktop "smears" (doesn't refresh) and shows no wallpaper
- by Cedric Reichenbach
Since a couple of days now, my unity desktop background smears everything, just like what old Windows versions were famous for:
Of course, I tried rebooting a couple of times. Also, I switched graphics driver and I tried to change wallpaper and theme, but none of them solved the problem.
What could be causing that problem, and where can I search on for its source?
