Quite possible. The FVF having position data is probably not very surprising,
and a FVF with diffuse data but no normals isn't that unusual by itself either,
but it may be worth a look to see if lighting is enabled or not when those
draws happen. I think lighting without normals may be slightly different
between OpenGL and ddraw.
