Mason Grid Blog page not working in Chrome

I have set up several pages to be blog-grid pages (grid style: Masonary, Page Layout: fullwidth)

http://www.cvillewinetour.com/cvilletravel/destinations-3/asia/

It works really well in IE. But in Chrome, the background flickers from white to black (depending on where the browser is)

They work fine when there is only 1 post for the given category (exmpl: http://www.cvillewinetour.com/cvilletravel/destinations-3/north-america/)

Is there a conflict with the featured images for each post and the background color call out?

I appreciate your help.
