WordPress 3.9 upgrade broke circular slider function?

I’ve had your slider installed for a few WordPress versions, but this latest update to 3.9 seems to have broken the circular slider. It’s currently experiencing jumps and other general weirdness. Everything works fine until I turn on the circular slider. Not an options to disable it.

Slider is on this site:
