@CenturyAvocado It is the (pre-modern-COSMIC) Pop OS desktop, the one that's GNOME with all the Pop OS extensions, but with some extensions disabled and some added. Come to think of it again, I didn't change a whole lot... maybe their build (?) of GNOME just doesn't work correctly with "Cosmic Dock", "Cosmic Workspaces", "Pop COSMIC" et. al. disabled.
