Hi Ben, thanks for testing.

Do you see the lines in the plot window? Is this only when called
figure(1), clf() before plot or does this also happen when calling
plot(rand(3)) alone?

Please try:
plot(rand(3))
print -color -deps junk.eps

This bypasses "gs" and stores the ouput of gl2ps directly.

Then please try
drawnow("eps", "dummy", false, "junk2.eps")

Which does basically the same as print -color -deps but doesn't do a
resize of the canvas before drawnow which could be a reason for timing
issues.

If it's a timing issue you could add

draw ();

in OpenGL_fltk::print just before glps_renderer rend (fp, term);


For the MXE build we have a bug report #42534 "No lines when printing
plot (fltk)" which perhaps could be related.
