mirror causing flickering black images

[Redglyph]

DCS 2.5.5.41371

 

With the mirror on, I get a lot of black images flickering on the whole screen, in circumstances that are hard to pinpoint but that seem related to the direction the plane (or the mirror...) is facing.

 

I get this in a very reproducible way when I use the quick mission cold start at Vaziani, soon after taking off on RWY 13 (the sun being slightly to the left). If I do a 360, it restarts at about the same angle.

 

I could do an active pause when it happened and if I switch the mirror off, it disappears. If I switch the mirror back on, the bug reappears.

 

The nVidia drivers are version 397.93, this is a 980 Ti so I doubt there is much change in the drivers anyway.

 

The quick mission uses a P-51D-25.
