[Octave-bug-tracker] [bug #44478] test __osmesa_print__.cc-tst crashes on Ubuntu with Nvidia drivers

[Rik]

Follow-up Comment #47, bug #44478 (project octave):

Thanks Juan.

I'm attaching a patch that builds the simple_gl_oct function into core Octave
rather than having it as a dynamically linked function.  Somebody with an
Nvidia driver can apply it, compile, and test as shown below.

What I notice is that I get strange results for the Qt toolkit even without
the Nvidia driver.  This makes me think that maybe there is something else
Octave is not doing when it initializes OpenGL through Qt.

See below for a series of test commands and the results on my computer.


graphics_toolkit qt
plot (1:10)
simple_gl_oct 
ans =  32610
close all
graphics_toolkit fltk
plot (1:10)
simple_gl_oct 
ans =  24


24 makes sense, 32610 does not.
