Hmm.
IIRC, the Unichrome driver does not explicitly wait for 3D engine idle before
doing a back-to-front buffer blit, since this would probably involve making DMA
quiescent and doing a busy-wait on the 3D engine.
Rather, it assumes the command regulator waits for 3D engine idle before issuing
a 2D blit.
This might well be the cause, but then this would have severe performance
implications in very important applications such as glxgears ;)
We should really figure out wether this is the case.
