I run an AMD R7970 on DX11 windowed mode (which i then double-click to make fullscreen - i have to do this to limit the refresh rate to suit my monitor) and report that, while I havnt experience the exact same issue as OP, I do do experience times where it looks as though semi-transparent textures arent rendering. I first noticed this on the Egis, but then also where player's weapons would normal glow they werent or only partly. And I dont know if its intensional but I find that in cutscenes the surfaces all look very bland like no shine to them.

Now you mention it I too had that but I've seen it in other games too so dismissed it as just 'one of those things'
