Yep, both views seem to be stuck on the left side... Also, not sure if that is a bug, but UI is almost unusable with that option.

I won't use the UI in this mode of course. I tried to setup a fullscreen viewport for previewing on 3D-TV.

It is definitively a bug. I spent some time investigating it, I believe it has to do with wm_draw_window_onscreen and how it calls wm_draw_region_blit.

@Brecht Van Lommel (brecht) have any suggestions on where I could/should look at?
