How to solve the problem with the slider?

Question

css

Hello, please help.
There is a site - http://ava55.esy.es you need the slider to work like here http://ava.sibirrez.ru/
It seems like it's all about .section { background-attachment: fixed !important; , but when I apply it on the 1st site, the pictures fly away.
p.s. Weird bug when using background-attachment: fixed. Is there a solution? I found a solution here, but it did not help me (or I'm doing something wrong)

Answer 1

Maybe just the wrong transition effect is selected? there seems to be all sorts of things, see the backgroundsFixed.html example from fullpage.js
