Comment 23 for bug 141533

Like Alfredo says, the issue solved for me after updating Gutsy to get xserver-xorg-video-ati version 1:6.7.194-1ubuntu1. Oh yeah!!

So now playing a video with Totem and switching workspaces works ok with Compiz (and moving the Totem window "retains" the video inside it, without leaving trails behind).

Many many many thanks to you, your work is very much appreciated!
