Odd. It was a designers dream (and a readability nightmare) but I didn't have an issue with scroll.
Firefox on Samsung S23, not exactly a new or a powerful phone but rendered it fine.

That being said, the scroll was as smooth as regular webpage scrolls. Usually these JS scrolls aren't able to avoid dropping frames or otherwise introducing judder, but this one does appear to run at a consistent and high framerate, which is technically impressive.
