Going into x11-drivers/xf86-video-intel and chaning src/i965_render.c around a bit helped. Turns out gen7_composite_wm_state still tries to configure too many threads. Changing the ps_max_threads to 42 from 86 eliminated the corruption I saw with blackbox. But there are still lots of artifacts with video. - alex
