This was true before XFree86 4.0.99.2 due to bad interaction between GNOME and
the old shadowfb implementation which copied the whole area around the damaged
region after each operation.

I have gotten a patch into 4.0.99.2 which not only remedies this by switching
to the new mishadow layer which only updates the framebuffer contents
periodically, it also adds RENDER and DGA support to the fbdev driver.


Maybe it will get available soon as .debs through the DRI packages...
