[Octave-bug-tracker] [bug #47217] After image/imagesc, the body of a patch is not drawn under FLTK

[Rik]

Follow-up Comment #3, bug #47217 (project octave):

This may very well come down to different software versions and also different
HW drivers and their support for OpenGL: neither of which is specifically an
Octave problem.

Does the plot work if you use the Qt toolkit and its interface to OpenGL?

I fiddled quite a bit with the Z-level offsets in order to get the widest
variety of plots to work correctly.  It was no fun so I am reluctant to do it
again.

For an example of what I mean, I applied your patch and then ran 'demo
isosurface'.  See the attached plot and you can see that the lines of the
various patch objects in the isosurface are partially obscured.  This doesn't
happen for me as things stand.
