Ah, yes - this actually has nothing to do with anti-aliasing, but is a 
side effect of various changes to the alpha channel handling introduced 
with 3.7.beta.38, which apparently break down in case the resulting 
transparency is exactly 1.0 (as opposed to e.g. 0.9999), and generally 
don't play nice with colored yet transparent background colors.

I guess it's back to the drawing board for me.
