Yep, you're rendering on your CPU :/

What does your Xorg log look like?

What command line should I use to check the Xorg log?

https://askubuntu.com/questions/26525/where-is-xserver-log-file-located

So, for example,
cat /var/log/Xorg.0.log

and

cat /var/log/Xorg.1.log.

Which kernel is the default on Pop OS?

PopOS 20.04 uses the 5.4 kernel.

I don't know. But I just installed mine about 2 weeks ago: 5.4.0-7642-generic

Michael from Phoronix is talking about using these CPUs with kernels 5.6-5.7. I’d say something newer than 5.4 is needed.

I may have found the text line to confirm the problem:
At some point in the log file it says this:

[ 65.119] (II) UnloadModule: "radeon"
[ 65.119] (II) Unloading radeon
[ 65.119] (II) UnloadModule: "vesa"
[ 65.119] (II) Unloading vesa

Both log files can be checked here.

damarrin - It seems that marvelgg from Pop! OS Reddit agrees with you:
"If it is a recent AMD CPU/GPU you may need a newer kernel for it to work properly. You can try xanmod.org STABLE branch or use Mainline app if you want to keep using the Ubuntu generic builds for some reason"

So, I guess I should look into upgrading the kernel (?)
