Follow-up Comment #5, bug #45881 (project octave):
I think this issue is not related any OpenGL, but Ghostscript related, since
going through gnuplot makes the same result, but rectangles instead of
triangles. The problem is that Ghostscript is anti-aliasing on each polygon,
instead of the entire output image. This results in ugly artificial boundary
conditions.
Even though this particular bug belongs to Ghostscript, Octave still needs
internal print functionality to properly images with different shadings (or,
is it possible to use smooth shading in postscript?)
