Rendering on https://jakearchibald.github.io/isserviceworkerready/ is very slow if you scroll via the scrollbar.
Marco if you have some time to spare, could you record a profile of the issue using the gecko profiler addon? This page scrolls fine for me, so it'd be interesting to see what's causing the slowdown on your computer.

Thanks! The profile shows some pretty bad jank in the gradient painting code.
