Because you also have this problem (on Win with MXE build) without my
patch (if I got this right on savannah) on default and all works for you
if you revert gl2ps-renderer.cc to the last stable version, I doubt that
this has the same origin as Bens' problem

This might be richt, we are doing
      // For 2D plots we can use a simpler Z-depth sorting algorithm
      if (term.find ("is2D") != std::string::npos)
        gl2ps_sort = GL2PS_SIMPLE_SORT;

And the docu says for this:
GL2PS_SIMPLE_SORT
    The primitives are sorted according to their barycenter. This can be
sufficient for simple three-dimensional scenes and/or when correctness
is not crucial.

I think correctness IS crucial for our 2D plots. Can you try GL2PS_NO_SORT?
