New Website for B2B payment provider

Here is a website I finished some time ago: https://remipay.com

As I was very hard pressed for time, I finally had an “excuse” to buy into Eldars templates and courses. His templates can really be a huge timesaver!

Any ideas how I could reduce the jitter of the hero images in Safari?

remove parallax effect

OK, reduce jitter and keep the parallax effect, is what I meant.

It looks fine in Chrome and Firefox, only in Safari I get this jitter.
