I'm new to ScrollMagic and GSAP, and I've run into a problem with a site I'm making. The second section is all parallaxing clouds, with the section being pinned at the top of the screen.
The issue is that on the pin trigger, there is a 'jitter' that happens, which (I'm assuming) is caused by the horizontal scrollbar showing up. If I hide it, there is a vertical scrollbar within the section (also not desired).
After some testing to narrow down the problem, I have found it only happens when the cloud in the section flows off of the right side of the screen. I need the overflow-x to be hidden while having overflow-y visible, to go with the design of the site.
