Screwy Skinz

OK, I've tried just about everything here. After this last update, I am having major issues with my skin. If I change my hair, my face scrambles. If I put clothes on, I get black squares all over my body. Ive tried changing skins, and it works for a minute, but then the black squares come back again. The only time I look normal is if I walked around naked all the time :| Not gonna happen.
It seems to be that if I put a skin on, take all my clothes off, relog, put new clothes on, Im fine. But the second I try to change into anything else, black squares! UGHHHHH
Every update seems to ruin something else.

try turning down your options , then up, friend of mine had something similar, to high settings and started to get wierdness on her char.
