Any idea regarding the reason for this behavior?
P.S. I noted that glxgears renders OK on fullscreen with fglrx->radeon. In window it's wrong.
Unfortunately, I didn't see anything obvious in the dump. Can you try my drm-next branch? http://cgit.freedesktop.org/~agd5f/linux/log/?h=drm-next-3.10 Does that help?
