TearFree should be much improved as of:
commit fa2687bdd5a4c8bc608dac8bb711035f0752a725
Author: Chris Wilson <[email protected]>
Date: Mon Oct 21 18:55:23 2013 +0100
sna: Eliminate the synchronous wait from inside TearFree
Defer the actual wait until the next use of the screen pixmap, and then
if needed replace the GPU bo with an alternative back buffer.
