--- Comment #7 from Hans Nieser hans@nieser.nl --- With kernel 3.6.2 and xorg/mesa/libdrm from git the object selection problem is no longer occuring on either my 4850 or 5850 radeons with r600g (has probably been fixed long ago since I've used blender before on occasion without this issue). Lighting is looking correct as well
