Two copies of the wallpaper running simultaneously [video]

[Szymon Waliczek]

This is fresh and updated install of Ubuntu 12.04 LTS.

It's ruining fine but after some time the wallpaper is defected.
Its occur on gnome 3.4.0 didn't experience it on unity so far.

I'll live it as it is so if you want me to do further testing no problem.

This is fixed if you upgrade to gnome-shell and mutter 3.4.1.
