[Octave-bug-tracker] [bug #44916] Printing Qt-drawn figures produces faulty files

[John W. Eaton]

Follow-up Comment #14, bug #44916 (project octave):

I've done some more investigating and it seems that on systems where this
problem happens gl2ps is getting a bad set of points from the OpenGL buffer. 
Strange.  It also seems to affect printing with FLTK, so it doesn't seem
likely be a threading issue.  And it worked previously in 3.8.2 with FLTK.

I'm still unable to duplicate the problem, but the person I've been working
with might not be able to help more until next week.  If someone who is
experiencing this problem could help me with debugging before then I would
really appreciate it.

The first thing I need someone to try is to install
ftp://alpha.gnu.org/gnu/octave/octave-4.0.0-rc4-installer.exe and then verify
that there is a problem with printing the plot


plot (1:10)


(missing axes lines or missing segments from the line).

Next, exit Octave and replace the file bin/liboctinterp-3.dll with the
following version: http://jweaton.org/liboctinterp-3.dll

Then try to print the same plot(1:10) graph again and see if the generated
file looks correct and report the results here.
