The results varies - sometimes, you can get only an unpleasant flicker, but also a brutal flashbang blinding you. It depends on the time of day, the weather and part of the map you're using.

At the moment, I can confirm that the problem is present in both Cam Lao Nam and Khe Sanh, but I was able to localize the place where it's most obvious/easiest to reproduce. You can find that in my showcase mission.
