[Octave-bug-tracker] [bug #50612] warning: opengl_renderer: Error 1286 occurred in init_gl_context

Follow-up Comment #2, bug #50612 (project octave):

Hello!  

I am also getting this error when installed octave via homebrew using the
default qt graphics toolkit.  

I am simply trying to plot points overtop a matrix image using the code found
at 

https://www.gnu.org/software/octave/doc/interpreter/Plotting-on-top-of-Images.html

What I am getting is found in Figure 1 (the image takes up a 1/4 of the plot
window instead of the entire window).

I have posted the same issue at 

https://computergraphics.stackexchange.com/questions/5024/octave-matrix-to-image-pixels-too-small-do-not-have-1-pixel-per-integer

if that helps.  I can't seem to find anyone else with the same problem, any
help would be greatly appreciated.  

Also, when I use graphics_toolkit("gnuplot") I can plot matrix images
perfectly until I plot overtop of them, then I get the following error with a
random pixellated image

multiplot> B
           ^
           line 0: invalid command

Thank you and let me know if there is any more information I can provide.
