Parallax Scroll Locking up

Hello, new to webflow. I added parallax to a number of the elements on my site, and it mostly works! One issue: the scrolling seems to randomly lock up. Can’t get it to scroll smoothly.

Here’s a link: 0xpo.weblow.io

I’ve found issues that are similar, but I can’t seem to find anyone else with this exact problem. Any advice would be greatly appreciated, thanks!
