We are not doing anything really special for freetype fonts. 

There is however one change we did inside Qt between 3.2.2 and 3.2.3 that 
affect font rendering, when you're using a 75 dpi display. That fix might 
lead to slightly smaller fonts, but they are usually a lot better readable.

The problem was that Qt 3.2.2. requested non integer pixels size from 
freetype, leading to rather some fonts being rendered rather ugly (at least 
with my version of freetype, and I was this on some other machines as well). 
This has been fixed in 3.2.3, and the sizes we request from freetype are now 
always integer pixel sizes.

What kind of incorrect behaviour? I couldn't find the patch or change you're 
talking about in recent mails to this list.

To be honest, I can see that the font got smaller (which could be my change to 
Qt 3.2.3), but I can't see that rendering in itself got worse.
