Here another profile using the Graphics preset: https://share.firefox.dev/3Nnvcr3
The news section is more or less smooth, but once you reach the comments section at the bottom of the screen the scrolling becomes stuttery.

Thanks for the report.

The comment section uses backdrop-filter which unfortunately causes known performance issues for us. See comments in bug 1891831 which seem equally applicable here
