Bushwick keeps 3D effects from working in Chrome

I am busy creating a slider with Master Slider. In this slider, you can use a number of animation effects, which rely on 3D Javascript/CSS code.

These effects work fine in Firefox, Safari, and (mostly) in IE. However, in Chrome they are not working.
That is: the effects are working in the preview option on the admin interface, but not on the live page containing a slider. I have looked into this with support of Master Slider, and they said that it is some code in the Bushwick theme that is blocking the 3D options from working:

The functions that check browser for supporting 3d CSS effects returns false (Just in this case). But it should returns true in chrome.
So it seems there are some scripts that affects on CSS 3d effects.

When I temporarily switch to the default WordPress theme (TwentyFifteen), the 3D effects are working in Chrome too, even on the live pages. So it really must be something in Bushwick.

Does anybody have any idea how to fix this?
