Public bug reported:

Binary package hint: xserver-xorg-video-intel

Since upgrading from Lucid to Natty, font rendering in firefox and some
other apps is buggy. Certain letters in certain fonts will be missing
pixels from horizontal lines through certain letters. For instance, in
the screenshot I'm about to attach from this bug report, all the 'o'
characters are missing a line through the center, and 'n' are missing a
line a little below center. It's different every time: if I restart
firefox, different letters will be affected.

Graphics is Intel 915GM (on a Sony Vaio TX650). I don't know that it's
the X driver at fault, but most people who see the problem seem to think
that it's related to the video driver rather than the font rendering
libraries. Changing my set of installed fonts or changing to a different
default browser font can make the problem better or worse, but never
makes it go away entirely.
