scrollify and malihu-custom-scrollbar-plugin on touch devices - jquery-scrollify

Question

I'm building a website with vertical split screens and full viewport sections. Each section is divided in half where every side can have overflow content. When theres no overflowing content, the page should scroll to the next section. When theres overflowing content, it first should scroll to the bottom/top and then to the next/previous section.
For scrolling through sections I'm using scrollify. For overflowing content and nice scrollbars I'm using malihu-custom-scrollbar-plugin.
On desktop everything works fine, but on touch-devices its very buggy. Unfortunately I cant figure out why and how to prevent this buggy behaviour.
I've created a Fiddle
Maybe someone could point me in the right direction?
