Well after reading like 10 different websites, it seems like the problem was because of negative padding and margins, but i did not used negative values at all… so the WTF!!, anyway, you can grab the solution right here:
Chage:
_default:function(a){a.elem.style&&a.elem.style[a.prop]
by:
_default:function(a){if(isNaN(a.now)){return;}a.elem.style&&a.elem.style[a.prop]
