[Octave-bug-tracker] [bug #48669] Segfaults at exit after using OpenGL-based toolkits in --no-gui mode

[Dan Sebald]

Follow-up Comment #8, bug #48669 (project octave):

xserver-xorg-video-nouveau
Version 1:1.0.10-1ubuntu2

does not crash in either the FLTK initialization case or the Qt at exit case.

However, the FLTK plot looks like renderer screen garbage.  (I'll attach a PNG
of both.)  Now, Nouveau is an "experimental" driver in the sense that
developers aren't 100% sure about how to control the hardware.  But Qt toolkit
works.  I'm not seeing anything else on my system graphics failing (but I did
notice a one-time screen flash when I created some plot in gnuplot running on
its own that I don't see with the Nvidia driver).

On my system, I see libfltk-gl1.3 1.3.2-4.  I could try version 1.3.3 from
scratch.
