Which version of Corona you are using? and it would be best if you can send your scene to us by starting a ticket so we have a quick look and provide you a solution.

HF1.  It happens in the simplest of scenes too.  I'll do a video today

For clarity, you mean the Volume Effect checkbox in the Corona Sky? This is not actually a volumetric fog, just a quick effect that is much simpler than anything truly volumetric which lets it be as fast as it is - but as such it comes with limitations that would not exist for an actual volumetric material. Not meaning to be "nit picking" but it's important for us to know if you mean Volume Effect or volumetric fog, since the two are different :)

Yep that's the one.  So it's a bug or just that it has a downside?

This is most likely a known bug. This kind of "white band" appears when the volume effect is combined with some other effects, such as clouds or visibility overrides.
