>> appears jagged in Chrome 23 on my Windows 7 machine, with ClearType configured.

Same here.

I have a Stylish script configured to render "safe" fonts every time I am "forced" to use Chrome. Chrome is also very memory intensive on my machine (4GB RAM anyway!)

This font rendering bug is really such a long running joke on Chrome that it might just end up being elevated into some kind of "this is no bug, this one is a Chrome feature!" /frustrated
