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?

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


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 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 (?)
