Hi Philip, thanks for testing

Interesting. The bug report I linked is, that no "data lines" were
generated but axes, grid and so on are visible.

gs versions >=9.09 have removed pswrite
( so If we
suggest 9.14 this would break PS output.

I remember that I've chatted on IRC with someone who reported problems
like missing lines when printing. After he updated the drivers for the
graphics card this problem was gone. So this was only a wild guess that
the driver might also be a source for problems. Btw: We also have
display issues with OpenGL in the bugtracker which are only visible with
AMD GPUs, Nvidia and Intel renders fine:

Thanks again, Andy
