Hm, maybe it's the border-image. For me, specifying `background-color: transparent;` to `#home article` fixes things right up, at least in firebug.

Yep, and then, if I recall (and without looking), it removes the background on Chrome entirely (leaving it transparent and grey and unreadable instead of white in the center).

I messed with it for a couple hours to get Chrome and Firefox to render the same and eventually gave up and moved on to more important things, but it's on my list to investigate.
