That's odd, because the object rendered in 3.1 with AA is placed exactly at
0, 0 and the camera is looking at 0, 0 and the object is rendered quite
symetrically. Notice the cross at the center of the circle; the pixel colors
representing where the edge lies seem equally bright both left and right,
and top and bottom.

The thing I'm referring to is that those same edges are very rough and
ragged looking in 3.5.11, but smooth looking in 3.1. Actually, it's not just
the edges, but the black material is less uniformly colored in 3.5.11 and
maybe that's affecting the edge with the yellow material. In fact, the whole
image looks a little bit blurry or softened in 3.1, but quite a bit sharper
in 3.5.11.

So I'm thinking that could be a change in the anti-aliasing, but maybe it's
something else too. (like a different aperature, but I don't have focal
blurring intentionally turned on or off).
