I think I have the same problem when running in extended display mode.
It seems that the images are reversed; the image showing on the left eye are actually the one for the right eye and vice versa.
This makes me get a constant double vision, and is not really comfortable. It is only affecting vorpX; all the other demos I have tried so far works like a charm.
For reference I am on a intel i7 4770K with 2x780ti SLI.
