This website has unbearable scroll performance on mobile.

Is it the animation at the top?

We tested it in mobile, but several people pointed out that we have more performance work to do to make sure that the animation is fast on lower-end hardware. I don't know what phone you're using, but we'll get it fixed regardless.

1 more data point - it's very slow on my desktop which has relatively high performance as well. Using Brave if that matters.

We're about to push a change that should improve this a bit, thanks for the reports!

One more data point--I'm using Firefox on an M1 Mac mini (MacOS 15.7.7), and this web site destroys the responsiveness of this system in a way I have literally never seen before (4+ years) from anything, web site or otherwise.

I opened up Activity Monitor and CPU use looked normal but it showed the GPU was pegged at 100% as long as that page was open.
