It's strange hearing reports of "scroll lag" in the other comments. It's possible I'm just lucky. Or there's a misconfiguration somewhere in their setup that Chrome somehow avoids.
It's true that I still mostly use Chrome for webdev - I've become more used to it's (excellent) dev tools, even though Firefox and Firebug started that whole trend. It feels very right to separate my "user browser" from my "dev browser" in this way!
Don't forget the other possibility: someone using Firefox having internalized this lag as "normal behavior".
Have some humility.
That said, there is something to be said for modern applications just running way below the limits of the refresh rate of our screens: https://twitter.com/jmmv/status/1671670996921896960
