Follow-up Comment #50, bug #44478 (project octave):

I think what this simple example demonstrates is that one should not call any
OpenGL function when there's no OpenGL current context in the current thread.
Because of no existing current context, you're accessing garbage memory.

This is different in FLTK, because drawing occurs synchronously in the octave
thread, so there is an OpenGL current context.
