So this is somewhat interesting. Here’s the skinny:

• Let’s say you’re using a WebKit-based browser.
• Let’s also say that you’re mucking around with a little @font-face, along with a few other CSS shinies.
• Now, let’s also also say that you’re mucking around with -webkit-transition, a less-than-standard but still somewhat sexy stylesheet property—specifically, you’re applying a CSS transition to a link when the user hovers over it.

What’s the result? Well, if you’re hovering over the link while your text is being resized, it looks something like this:

So in short, -webkit-transition and @font-face produce a weird, freaky love child visual bug if you’re hovering over a link and resizing your text. The text will temporarily revert to the next non-@font-face font in the stack—Helvetica above—before re-applying the proper typeface.

Which, yes, I realize probably nobody will do. Still, I think it’s kind of an interesting little tic. Plus, it affects all WebKit-based desktop browsers I tested on, notably Safari and Chrome. Remove the @font-face assignment or the -webkit-transition, and the bug goes away.

Granted, it’s no systemic rounding error, but hey: what is?
