Odd logo glitch

This seems like a pretty minor bug, but a bug nonetheless, so I figured I'd share it.

Occasionally, the logo of the site will look like this:

Not sure what's causing it, as it doesn't happen all the time... and it is just text over the logo, so it's not like it breaks the site or anything.

Anyway, I'm using Windows 7, and the latest stable release of Google Chrome. :)

I only ever see that when I press CTRL + F to search for some text.

@chaser324: hmm... yes, that did make it show up, provided the first letter I typed was G, i, a, n, t, b, o, or m.
Although, I can't remember if I was searching for something or not, the last time it appeared...
