Follow-up Comment #5, bug #57651 (project octave):

Different behavior on different machines?  This bug is going to be harder than
I thought.  You can update the description if you are sure that the axes size
is the only thing that really is different.

One thing I see is that the "paperposition" property is different between the
first and second printings.  I can get both of the plots to be the same (in
other words, both are wrong in that the markers overlap) by forcing an update
of the paperposition property.


close all
graphics_toolkit qt
clf

h = plot (1:10, 'o-', 'markersize', 36);

## This forces re-calculation
set (gcf, 'paperposition', [0, 0, 1, 1]);
set (gcf, 'paperpositionmode', 'auto');

print -painters -color print1.ps
print -painters -color print2.ps


This probably says that there is a race condition, or that we should force a
re-calculation of "paperposition" when printing and "paperpositionmode" is
"auto".
