Sorry that trace is a bit too much to handle. I looked at it but I can't really
make out any difference wrt use of glsl shader or not at all (note that for the
gallium driver this cannot make a difference in any case as it has no idea if
you used glsl or not, though in theory there could be slight differences
depending on how ftransform() is implemented). Just about the only thing I
noticed is that the actual geometry is different between the two... Could you
tell me at what call number this is?
Also it looks like it has depth test enabled as well, I'm not entirely sure if
or how clipping would affect interpolated depth, though nothing bad should
