started from terminal

Flickering on viewing a camera stream with activated hardware accelerated d3d11
setting is back. Desktop picture and camera picture is swapping.
It was gone with 10.0 stable - it's back with 10.12 (maybe some versions
earlier).

Software rendering works still fine.

regards, Andy

A regression test will help pinpoint the change in Wine.
