I've been building my app on Ubuntu with qt 4.7.1 that I built from source. The fonts rendered anti-aliased without an issue. Then I built 4.7.2 and 4.7.3 and built my app against each. In both cases the fonts are not anti-aliased.

I've done nothing else, so does anyone have any hints why the different builds have no anti-aliasing?

Thanks in advance.
