As the title says. Once you scroll down a bit, the images “jump” at a certain point.
I found a few posts from years ago with the same problem but couldn’t find what I’m doing wrong.

I noticed you use the same parallex effect 4 times; On section header , header home , padding global and also on case study image 1
Perhaps this causes some issues with the animation.
Thank you! That solved it!
