Hmm...  Plug this into the default start up and see what you get.  Why are there strange shadings going on up there?

I don't see any strange shadings, in the preview anyway. Can you show a render showing it?

There may indeed be a problem in 4.4.4.20 regarding light/atmo. I just opened a file from a previous version and the lake looked very strange in the preview. Normal without sun turned on, but the clouds make very hard shadows.

Thanks, Ulco!  This is what I mean.  Strange shadow-like features seem to be related to the clouds beneath.  If I disable the cirrus, it goes away.

4.4.42 was a Release Candidate, but it hasn't been pushed to the update checker so it's probably only the alpha testers who've seen it. 4.4.40 doesn't have this bug.
Just because milk is white doesn't mean that clouds are made of milk.

Rich, it looks to me like the cirrus layer is receiving shadows from the cumulus because it's semi-transparent and lower in altitude. If so, it's not a bug.

Matt, sir - you are correct!  Little did I remember that I had once lowered the altitude of the cirrus, almost to the same as the easy cloud.  :P   Now that I raised it, problem solved.  I should have known...
