I hope this is not the case .. but surely it could be, since it's not tested
due to the lack of available machines ..

I concur that.
And as Wade stated earlier, yes - I cannot make a statement about stereo rendering
right now, since I don't have a machine supporting it either.
However, if you can help showing us that we do have a bug within the selection
of the native GLX/WGL/.. pixelformat via GLCapabilities .. sure we love to fix it.
As we always stated .. a junit test is always the best start for any communication.
I for one, only use 'laying around' code snippets very rarely.
But if one offers some proper junit test, maybe even via a git patch/repo-pull-req,
I will have a hard time to defend my lazyness :)
