Uninstalling has caused dead pixel like artifacts to appear on my screen.

OS: Ubuntu 20.04

I ran through the installation on Ubuntu 20.04 using the master-jammy branch (installed via make local-install). I decided to uninstall via make uninstall. After uninstalling I noticed screen artifacts that look almost like dead pixels. At first that's what I thought they were.

They don't appear on the login screen but do appear on the desktop. They are definitely due to installing the pop-os shell because I can see the border radius on the screen artifacts that match the radius I was playing around with on pop shell. I was hoping something could advise on what I could try in removing them. I'm attaching some screenshots.
