Bug Description

On Precise (installed from the latest daily live image after beta1), the screen flashes on the areas where a repaint is ongoing. I suspect this is caused by a bug inside X driver or Unity. Looks like the HW 2D/3D operations doesn't get sync'ed well with SW operations.

I'm using an atom based netbook. And never met this on Oneiric.
