I at least pretty much agree with Eero here: vsync is a global problem that affects many applications, and cannot really be eliminated by editing just one of the pieces in the graphics stack: it has to be a coordinated effort.

In fact, you can easily see that there's still some tearing, albeit reduced, when removing hildon-desktop from the equation by either killing it or pressing Ctrl+Shift+N. While in this mode, you're neither using the SGX drivers, nor hildon-desktop, nor clutter, and yet there's still tearing that comes from Gtk+ and Xorg themselves.


Of course it is easier to fix in Meego, because Nokia now basically controls the toolkit.
