High CPU usage when using Facebook [edited]

Since the last 2-3 versions of the nvidia driver for Linux using Facebook with the new design causes extremely high CPU usage leading to the entire system to freeze for a short time - CPU at 100% and 60-65 degrees which is even more than when playing a game. I type a sentence and it appears in 20 to 30 seconds.

Googling for nvidia driver logs I found this script for creating a bug report which I uploaded here, hopefully there will be something in it to help resolve the problem:

P.S. IDK if it’s related but I gotta mention it anyway: using the AUR package facebook-nativefier makes FB run very smoothly and without system freezes - CPU runs at 2-5% load which should always be like that. I tried with 3 other different browsers - Pale Moon, Opera and Chromium and with them the 100% CPU usage is the same (my default browser is Waterfox), so it’s not a browser issue. I found a topic here from 4 years ago of a user with the same problem which makes me think it’s a driver problem.

Edit: using TK-Glitch’s script I just downgraded nvidia driver version to 450.56.11 and now there’s not a trace of the high CPU usage - Facebook and the CPU work together within the normal limits. So it’s definitely a driver problem!
