I'm still working on improving the general tearing problem (for all
graphics hardware) running compiz/unity in bug 880707. I am not fixing
gnome-shell right now.

Tearing is almost always a bug in the application (compiz/unity or
gnome-shell), and almost never a bug in the driver. If there is a driver
issue then it's usually that the manufacturer has decided to turn off
vsync support by default (which I think ATI did with fglrx and "Tear-
free desktop"). However, Intel have the feature turned on by default and
AFAIK you can't turn it off. So tearing with intel graphics will
generally be resolved by fixing the application, and not the driver or
X.
