I am facing a really strange behavour on a Symfony v4.4 MVC Application. The Frontend is made with twig rendering engine.
If you scroll down fast, the browser has problems with building the DOM properly.
Here is a link to the current version:
I think its even worser on Safari. On Chrome its a little bit better but also not good.
If any Symfony, Php, Twig expert has any idea, what i am missing or what could cause this weird behavour i would be very thankful!
