Parallax cuts image in menu

Question

I have a problem with my parallax function here The function itself works great, but whenever I scroll down to where a parallax image is (for example on one of the product pages), and at the same time hover over the top menu products, it makes the images disappear. From what I know, it only occurs in Chrome.

I know for sure it's the parallax function, because if I delete the parallax mirror div, it all works great again.

Have anyone experienced the same thing, or has a clue of why it's doing like this, please let me know!

EDIT: Hi, Here's a jsfiddle! http://jsfiddle.net/fxL7yq35/7/
