I suppose you have to tell fontconfig to do the right thing.

This is beyond my knowledge, sorry. I'm quite sure that you
are not the only one which has been bitten by `gasp' issues.
Maybe a search in the internet provides useful links. Otherwise,
the fontconfig guy of Ubuntu should give further advice.

Your graphics system isn't set up correctly. In the `gasp'
table of Verdana bold (I have used version 2.40 for testing) it
is explicitly written that you have to use NO anti-aliasing for
sizes below or equal to 16ppem.

Look at the attached image. The DELTAP1 instructions in line 61
and 64 explicitly move points 3 and 9 vertically away from the
pixel grid, assuring good rendering for non-anti-aliasing.

Take a look at the attached file. The uppercase O character is so blurry it looks bigger than all the other characters. It happens at 11px, and also at 10px, but it's not nearly as noticeable. Using Freetype 2.3.7, not sure if it's fixed in CVS, but I'm not going to enter onto dependency hell just to try, I'd rather wait for Ubuntu 9.04. Bytecode and AA are both on, 89x87 DPI.
