It seems that you're on the right track. When I switch to a window with "\", I get a 3D rendered video. The scaling of one eye view is off like you can see in my screenshot. But apart from that the behavior is exactly like you described.


Btw.: I temporarily also have a Nuc7i3BNH with Intel HD630 graphics for testing available. It behaves exactly the same as my AMD system, even the scaling issue is the same. So I'm quite sure we don't have vendor specific or HW vs. SW encoding issues here.
