I am seeing this too. Hoping HiFi can solve this and make it more "smooth" and better coloring too. Especially at Day/Night transition times this layer is becoming more appearant and more brown, which could be optimized as well.
But I like the work of HiFi so far! Great Addon and one of the most inmportant addons in P3D ever!
I really would like to see more and better cloud models and hoping LM could give them opportunities to do so! Also more cloud variation in the skies, like wholes and clouds mixed up in the field of view....not only OC or Clear or few all over the place.
As soon as LM gives HiFi the chance, I am pretty sure P3D will come back to life more and more, as this is a really lacking feature.
Thanks
@damian for keeping us updated so often!
