Images using :before :after element shifting

Great plugin. However one of our sites where we use a 3D shadow effect for our images it shifts the :before and :after elements down breaking the visual effect.

Here’s a screen grab showing the difference:

I tried enabling the responsive and retina settings but that didn’t help. I could not find any CSS that was causing this to happen, but disabling the plugin caused it to go back to normal.

We are using the latest version of the Vellum responsive theme: http://themeforest.net/item/vellum-responsive-wordpress-theme/6914246

Any insights on what might cause this and how to correct it? I really would like to use the plugin on this site.
