Yeah, I encountered the same glitch. At first I thought it was my GPU overheating or something, which has never happened, because the strange lighting effects showed up together with some weird artifacts when looking in a certain direction. I was at Balota airfield when this happened. It was the first game-session of version 1.7.1.1 and ArmA II Beta 93825 I used the "-winxp" variable with, because I read somewhere this could possibly have a positive effect on FPS (though I don't have multiple GPUs, just one). I don't know if this had anything to do with it, but I'll remove it the next time I'm playing DayZ.
