That's the sad state of OpenGL drivers for Windows, including the one 
published by a certain company whose name you can find in the signature of my 
email...

You could supply a helper application that you can launch and get the errors 
from, if you can determine what operations are causing them.

You mentioned three options ("desktop", "angle" and "software"), but only of 
two tests. I thought ANGLE had the best support, because it avoided the buggy 
OpenGL drivers and instead used the translation layer to get to DirectX.
