Issues with virtue theme

Hi there, been using your plugin for awhile and its been great thus far. Just switched themes to the free version of Kaden Virtue theme. It has an opacity on hover effect which seems to completely break your plugins functionality. Instead I get the second image and the main image both showing and nothing happens on hover. would you have any advice on what part of the CSS I might look at to fix this issue?

cheers

Harry
