Comment 1 for bug 454425

Do you have an ATI graphics card? If so, you may need to get the proprietary drivers as suggested in the neverball forums ( http://www.nevercorner.net/forum/viewtopic.php?id=1807 ). I have the same problem with the open-source drivers for my card (ATI Mobility FireGL V3200) and I haven't tried the suggested fix yet.
