I'm seeing the same things and in my case it has to do with Xorg hitting
fallback paths and using the CPU where it should use the on-card blitter.
This happens with the radeon driver (on an r300 based card) and the nv
driver (on a gforce 2mx). It seems pixmaps are stored in host memory rather
than the on-card memory which prevents the blitter from accessing them.
