Webkit bug YAY!

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?

    Well, they can’t all be systemic rounding errors, but that’s a good one to know. Especially since I’m diving into transitions now, and been fiddling with using @font-face more and more.

    This will save me the pain of discovering it myself.

    Bug? pssh…that’s what we here in the ‘how to make easter eggs out of comic sans” club call a feature!!

    Man, that’s weird. I used scale() on link hovers to some success on my site, but had to use display:inline-block to get it running, which was a little hacky. Worked with @font-face, though.

    Hi Ethan,
    the same Effect happens when you reload a page with Fonts included and on :hover when the hover-style contains the font description.
