Not really an OpenGL problem per se, more related to interaction between wxWidgets and OpenGL Canvas
I wonder how many wx apps are actually using OpenGL?

of the wxFrame which contains the GLCanvas seems a bit fragile at times, and definitely platform dependent... Sometimes they need a Refresh, and sometimes not....
Looking at cm93 Lat > 80 now. Can reproduce, so should be resolvable.
