Maybe it occurs more often with nice fonts, but it actually is a combined VM/image problem.
The VM prefers a 32 bit X visual (with alpha channel) over a 24 bit one. If a compositing window manager is used, the alpha channel is used for transparency, but the image generally does not care about the alpha channel in its frame buffer.
The olpc branch in the SVN repository has a fix for that, see

Thank you. Any chance to have this patch included soon in an official squeak release (as more people use compositing on linux) ?
