Can't decide whether or not this is a bug (Please see attached image). The banding COULD be a sort-of house-of-mirrors reflection of some bright edges, but I don't think I have ever seen this in reality for a simple piece of clear refractive material with parallel faces.

Did you try to reduce specular bounces (dl) or max depth (PMC) ? i think two or three would reduce this "mirror" effect another trick coul be to put less glossiness on second size of your glass...

Thanks, I'll give those a try once this render completes.

Wasn't sure. I've noticed two before (one for each side of the glass), but never more.
