Quicksand elements looking out of place on initial load

[lefadathe]

I'm having a weird issue with quicksand elements on my initial page load. http://bvh.delineamultimedia.com/?page_id=2 -> you may have to refresh a few times before you see what I'm seeing so I posted an image... http://i.imgur.com/026HYeH.pngIf you make sure your mouse if off of the page and reload it every now and then the quicksand elements are out of line as shown in the screenshot attached. I've tried debugging this but every time I look at an inspector the elements snap back into place. If anyone could help give me a clue as to why this is happening I'd be grateful! Thank you!
