I've had tear-free video (finally!) in GNOME 3 for a while now, using the following in my ~/.xsession (and launching that from GDM instead of GNOME directly): CLUTTER_PAINT=disable-clipped-redraws:disable-culling /etc/X11/Sessions/Gnome You may have to adjust the "/etc/X11/Sessions/Gnome" depending on your distribution (I'm on Gentoo).
