Then it's a mystery only you can solve.  Look at the definition of the
'region' face in faces.el: the only case where we use :inverse-video
is on monochrome TTYs.  If that is not your case, then I don't know
how to explain the fact that you see the region in reverse video.  I
guess I'm missing something, but what?
