Same problem. With amd and nvidia board. I just found that with nvidia (maybe also with amd i have to test) if go in Video Scaling Method is see that is set on Bicubic. I change to the next that is "Auto" and i have same problem. I change to the next that is "DXVA" i change to the next and anagliph works fine. all the next works fine.
Continuing to change to the next i arrive again to "bicubic" and still works. I change to the next again ("AUTO") and again no 3d.

Just to get it right - it's not working with AUTO and DXVA, others work, right? That's somewhat "expected" behaviour until we sorted this bug out.
