I do not remember you saying that it was slow only during wobbly. There
you get a lot of CPU usage due to differential equation solving and
pushing the vertices to the gfx card.
In both cases the whole screen has to be updated, not only the area of
change. That might inflict additional CPU usage as well. Other than that
everything's done by the graphics hardware.

Using XVideo with Xgl btw. uses OpenGL for color conversion.
