The corruption completely disappeared since I switched RenderAccel off (I'm using Human exclusively for 3-4 weeks now, didn't happen once). With RenderAccel on it's easily reproducible, by switching desktops or minimizing/restoring windows. It looks like a driver issue to me. BTW, EXA makes the corruption *much* worse on my system, compared with XAA.
