Same with a nvidia 660ti with 304, 331, 334 nvidia drivers on x64 14.04 + xserver-xorg-core_1.14.5-1ubuntu1_amd64. Downgrading to 2:1.14.5-1ubuntu gets rid of the tearing. Running xbmc in its own xsession with alsa. Problem only occours in XBMC.

I first tried downgrading xserver-xorg-video-intel to 2:2.99.907-0ubuntu2, which is still compatibile to xorg 1.15.0. The problem remained. Next I tried downgrading xserver-xorg-core to 2:1.15.0-1ubuntu1. Problem remained. Downgrading xserver-xorg-core to 2:1.14.5-1ubuntu4 and xserver-xorg-video-intel to 2:2.99.907-0ubuntu1, resolved the problem. I expect the problem in the upstream xorg version update, as there is no effective change between xserver-xorg-video-intel 2:2.99.907-0ubuntu1 and 2.99.907-0ubuntu2.
