Every next and back button click causes the three buttons to blink. I believe the fade effect is being applied to them when it should only be applied to the images.
Here is a page with the issue for reference, the enlarged images have the issue

I've confirmed this by setting nextEffect:"none" in jquery.fancybox.js which stops the buttons from blinking, but I still want the images to fade. How can I only stop the buttons from blinking?
I'm running 1.5.6.2
