Gmail Oddity in Chrome (Mac)

I noticed something recently in the Chrome browser (on Mac) that I thought I should share with the web.

When in Gmail, there appears to be a 1-pixel border around the entire browser window. This only happens when on the Gmail tab; all other tabs appear to have normal window behavior.

Look closely here, and see if this happens for you (if you are a Mac/Chrome/Gmail user, of course).

The top half of the image shows my Gmail tab active. The bottom is just a standard Google tab. Can someone forward this on to the Gmail/Chrome teams and get them to work together on this?  Because it’s really starting to drive me a little crazy.
