WordPress 4.1 and Boldial Theme

Hi, i have just updated wordpress to the latest 4.1 version and i have the latest update to the Boldial theme but when you go to move and element it causes the page to freeze and you can’t move the element. It just does some crazy blurred effect that freezes the element as mentioned by Bhremm.

I have contacted Visual Composer guys but they say that it has been updated for WP 4.1 but i can’t seem to update Visual Composer through the theme? Please help as soon as you can as this site is for a client and is hampering my work.

Many thanks
