Safari Navigation Width Issue

[DRE]

In Safari, on my site when you are the top of the page, the width is wider than when you are viewing the site below the navigation. This seriously drives me nuts and I can't figure out why. I've been going over my templates for months and still can't see what's causing this. Seems to be fine in other browsers though.

Checked in Safari and don't see an issue either.
