How do I do this? I'm currently just using the default, gray "3D" window
decorations.

I'm currently using 2x2 pages per desk on two desks, but I tried that
and there was no significant speed improvement.

I've tried those and they don't really seem to do anything. I've even
tried to tell X to use/not use backing store, and FVWM is still pretty
slow (more like choppy).
If it helps, I'm using X4.1.0 on a RadeonVE with a desktop size of
1600x1200 and 24bpp.
Thanks.
