What GPU do you use? It almost works in my environment except for that it needs 'Reset Figure' to draw. Without 'Reset figure', the plot area is filled gray. My GPU is GeForce GTX 750 Ti.

Unfortunately, LIBGL_ALWAYS_SOFTWARE doesn't behave the same everywhere, since the set of GLX visuals available with it is based on those available for direct rendering. This seems similar to [1], which I made some changes in libGL to try to address, but unfortunately that seems to never been resolved to a root cause. The "Insufficient GL support" message comes from octave, but since it doesn't say what GL support it needs but thinks is missing, it's hard to tell what the problem actually is. I guess finding where that comes from in the octave source code would be a good starting place.

(Everything should still work, using the software OpenGL renderer, as if the X server was started with -nowgl) But this doesn't seem to be the case, if a native Windows octave can find the hardware OpenGL renderer, which is a bit confusing.

I launch VcXsrv with or without native opegl, the fltk graphics_toolkit works fine for both cases. Mmmmm, GWSL uses VcXsrv for X server ????
