Tabbing out and back in or changing HDR during night mission without NV makes the screen white and blue.
When I do this, the screen gets all white with blue "shadows". If I lower HDR then it gets darker blue or red. High HDR brings back the white again.
This only happens during night missions.
Turning NV on/off removes this graphics bug. {F18331} {F18332} {F18333}
This also occurs when I changed the Anti Aliasing during MP. Changed to 8x and BAM. Didn't go away either after changing back!
I get this problem and I can fix it by pressing my NV button "N". If I press it again to go back to regular non-NV view then the white/blue problem is gone.
Like I posted in the ticket "Turning NV on/off removes this graphics bug." L33CHW33D.
Anyway, if I play a mission without NV this is a real problem.
Temporarily remedied by exiting to main menu (which is a daytime mission) and going back in. But right after alt-tabbing out and in it gets always messed up again.
