Michel,

After patch removal indeed page flipping started to work so no tearing anymore.

Unfortunately now I see problem with 2x DI. It manifests as jumpy playback.
This is typical when DI is too slow to keep frame rate. I have identical effect
on Nvidia's ION1 with Advanced 2x DI (ION1 is too slow for this advanced DI).

Mythtv reports:

(too slow), dropping frame to catch up.

It looks like 2x DI problem is only with enabled glamor - as on Brazos with EXA
2x DI works perfect. Also on Kabini it was working OK  - but it was OK when
page flipping was non-functional. I didn't test Brazos with glamor yet. 

I done tests with mesa 10.2.8/10.3.3 and xserver 1.16.1/1.16.2 In all cases
glamor 2x DI issue is present.

If You want to see issue visually - I have short video clip with issue...

PS: is it possible that DI issue is because playback window coordinates are -1
?
