Direct3D coordinates are flipped compared to GL coordinates, so it
certainly sounds like a something that could go wrong. You didn't
explicitly mention if you are rendering offscreen with the second
viewport as well, but I'm assuming you are.
Could you write a minimal test case to reproduce the problem? My
initial guess would be that
is the relevant code, but depending on the offscreen redering mode
selected (in wine) there are potentially other places where things
could go wrong as well.
