I seem to remember a case similar to this in Indigo forum -quite a while ago- but I dont think it was a bug.
Perhaps a normals, doubles, intersecting geometry issue?

I have got an indigo license, but I have not used it for a long moment.
If I remember well, in indigo you had to make the content of the glass intersect a little bit with the glass itself.
Weirdly, on the opposite, if the glass was intersecting a bit with the table surface, half of the glass was completely black !

I couldn't find any references for glass with that particular shape to compare ... Also the thickness of the glass influences things.
As for the patterns in the second render, I can actually see similar things in a real glass here. What I meant by the environment is, if it's just a black background with some white dots on it (just guessing, I don' have the hdr image here), there isn't much to reflect, and you can see all kinds of strange patterns.
HDR is black with large softbox lights, so that makes it more dramatic, but I guess I will have to stop doing subserfs of squares for my circles from now on
