Nice font and theme! What font is that? What dpi? What freetype version (with or without bytecode)? What theme do you use?
The theme I am using is a slightly modified version of Darkilouche as the application theme, and Gilouche as the Metacity theme. I changed the orange(#f57900) in Darkilouche to red (#e30800). I switched back to Darkilouche after having trouble with Firefox and Neutronium.
As far as the font goes, I’m also using the Liberation fonts with freetype 2.3.4-3.
