Weird Mac OS X Font Corruption

2006-10-31 12:03:15

Every now and then, if I have been logged into my machine (Mac Pro, OS X 10.4.8) for a few days, I get weird font corruption. It affects a single character, usually a "t" or a "\"

And it affects all my apps: emacs, terminal, etc that use that same font (in my case, Monaco 10pt.)

See the goofy back slashes:

Then log out, and log back in again:

It's creepy, and annoying, because it takes a while to figure out why things on the screen don't quite look right.
