On a bootstrapped Mac running XP, I get a situation where avatar skins 
look cloud-ruthed indefinitely, when
I set anti-aliasing on. No crashes from that specifically, though it 
seems a tad unstable overall.

If I turn anti-aliasing off, the avatars revert.

On the same Mac running Mac OS X 10.5.7, I don't get visual artifacts 
(just drastic slowdown) at any setting,
but sometimes, the scene goes completely black or close to it, and I 
need to TP to correct the situation.

Occasional random crashes when I'm testing on MacOS X, but nothing 
obviously reproduceable.
