A freetype font mystery

[Seb James]

Hi List,

I've been moving from a rather old version of X on a thin client device
we sell to something more up to date.

Having moved my dev system to an Xorg pulled from the git repository,
I'm seeing some odd features in the font rendering and I was hoping
someone could suggest what is up.

Here is an example image of a program showing the problem:

I've marked with red dots all the locations where the glyphs are
mis-rendered.

It looks like gtk+ is making too little room for the glyphs.

How does gtk+ know how big the font is?

I've tested this with gtk+-2.4.4 (the old version we used) and gtk
+-2.8.13 and gtk+-2.12.10 (which is the one shown in the image).

In each case, fontconfig was pulled from the xorg git repo and freetype
was version 2.3.7.

Can anyone suggest where I should chase this problem? I'm at a loss on
my own.

very best regards,

Seb James
