I have never had any success with a system OSMesa and VTK. I build a
copy of Mesa with OSMesa from source in my home directory. This works
just fine with VTK.

The Mesa libraries shipped with Fedora at least are built to support DRI
and hardware acceleration. This disables OSMesa. The OSMesa library is
built separately and does not seem to work with VTK.
