Hi. I installed the latest build 8045 today and found this grey-ish haze layer in almost every flight which presents around 4000ft-4500ft in CAOVK condition. In some other cloudy or foggy area I can see this layer becomes thicker and darker, visible all the way up to FL340. Is this normal or is there some setting I missed? P3D 5.3 HF1, EA on.
