Probably is.  If you disable the two inner layer, it's normal speed.
If you view just one inner layer, it's slow.

Lesstif has a "thindraw polygons" option that does basically that.
Unfortunately, the clipper makes it useless because it doesn't know
about the flag, so you see hundreds of polygon slice outlines.  I need
to move all the thindraw stuff to one place to get that functionality
back.
