Website lagging on mobile (Maybe a simple fix?)

Hey Guys,

while developing a landing page for our client, we noticed today that the landing page doesn’t run smoothly on mobile. The interactions on the page are largely minimized on mobile and there are not many interactions overall.
The jerking and lagging occurs on our iPhone with both Chrome and Safari.

Do any of you have an idea for a cause that leads to the judder? Maybe we missed something?
Here is a screencast from the iPhone: - Google Drive

P.S.: We have also tried disabling Interaction in Hero. However, that did not fix the problem.

Thanks a lot for your ideas!
