I discover on this post http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=561206#30 about rendering problem with Gnome-Shell and ATI something that make my Unity ( and my gnome shell too) a little bit better ( but still impossible to use) : you launch unity ( or gnome-shell) from a terminal, with this before : CLUTTER_VBLANK=none
example : CLUTTER_VBLANK=none . Maybe this is a clue that could help to fix this ATI relative problems!
