It seems that the right CSS animation classes are causing a double page width in Chrome for some reason, I've attached a screenshot. It will do it on the demo server.

Update: Using animation class with Big at the end (such as fadeInUpBig) creates whitespace at bottom of homepage on Cashmere. Removing Right/Big animation classes fixes all issues in Chrome.
