Small comment on my previous post: apparently enabling UXA with tiling causes a lot of the known UXA-related bugs to resurface. Rendering is faster with UXA, but sometimes it seems that the driver decides to stop rendering - I would resize something and suddenly everything will stop and the screen is not updated except for the cursor. Switching to another vt seems to reset it. I switched back to the default EXA and performance is the same as it was in intrepid.
