Proof? I don't know, but anecdotally... My late 2013 Macbook Pro Retina is still my work machine, I attach it to two screens, one of which is a 4K screen. Firefox struggles to play embedded video on that screen. Chrome does not. FF also seems to have a lot of weird copy/paste issues with the Slack web client and Jira.
I really don't want to use chrome but FF ended up annoying me so much I went back to it.
(Safari almost worked... but the outlook webmail we use didn't play well, and with safari I had to refresh and re-login every hour or so, rather than daily on other browsers)
If this sort of experience is true for most users, then it's bad.
