There's a similar bug in NWN2, but I figured that i was related to shadows(which many version ago already had a general problem even under windows + nVidia card--thought that it may have re-appeared), and the fade in/out of objects..
(This was under 9.7 + Ubuntu 9.04 x86-64, haven't played it since installing 9.8, but AMD also forgot to include part of the package, a prog/script to escalate CCC privileges in Ubuntu, solvable by pre-pending gksu to start up in menu item. Needed this right away since catalyst has memory problems wrt Desktop Resolution...)
