Comment 45 for bug 755841

Just adding myself as a 'me too'. Video tears heavily, and it does not matter whether compositing is turned on or off, the tearing is the same.

I would also like to point out that 'SwapBuffers' is enabled, which as I understand should prevent any video-tearing. However it does not seem to work for some reason. Xorg log contains the following on 'swap':
--- Xorg.0.log ---
[ 13.803] (**) intel(0): Framebuffer tiled

Other logs don't seems to have anything useful.
