GNOME Bugzilla – Bug 705757
temporary wallpaper change during overview
Last modified: 2013-08-18 12:30:59 UTC
When entering the activities menu, the background changes to something else, for example, my background is a picture of a rock, and when entering the activities menu, it will change to another background, like the 'good-night' background in the Adwaita theme's wallpaper collection.
I also have this. Looks like bug #705559.
I think this bug only happens after the wallpaper is changed ~3 times, then the overview is entered
