Hot take: if you want to use Cosmic Desktop, you should not use Pop_OS! But instead use Origami, Fedora Cosmic Spin, or CachyOS with Cosmic Desktop.
Pop has a pretty long history of bugginess and it’s based on Ubuntu which has a pretty long history of bugginess (especially with respect to graphics cards and system updates)
Origami = opinionated, dev-centric Fedora atomic spin with cosmic
Fedora cosmic spin is just Fedora but with cosmic instead of Gnome or KDE
CachyOS is a polished Arch-based distro with quick and easy setup and one click setup for basically every desktop environment or window manager
