I know this bug. I always thought that it isn't necessarily caused by
bad antialiasing, but rendering of everything except for the
background and overlaying it. Thereby effectively drawing over the
existing rendering, and since the overlay is not entirely opaque
(there are some partially transparent pixels) we end up seeing
something that looks like bad antialiasing.
I don't really have much to support this theory, except the fact that
it really could produce what we are seeing, maybe it is a total
misconception of the problem. Any thoughts? I'd really like to get
rid of this, it is annoying.

I know exactly the artifacts that your referencing, and it shows up
in more than just line drawing. Look at the following text, drawn
first at rest, then after a slight resize:
good text (right after startup):
<good_text.png>
bad text (after resize):
<bad_text.png>
I originally had thought that the problem was with button opacity
(that is, maybe it was claiming to be opaque, but really wasn't) -
that wasn't the issue.
Have you done any tests to come to this conclusion?
