I just noticed this breaks page flipping here (rv250), obviously with
xaa only (heavy flicker). This is without the drm patch, but I doubt it 
makes a difference. To be more exact, the 3d window itself is fine, just 
the window borders, background etc. flickers, so it looks like the 
refresharea stuff might no longer be working.
