the issue I have had with PopOS is multi-monitor support, I cant rotate my rotated second monitor except through the nvidia settings, and my settings get wiped after a reboot, its a known issue for years, other than that I havent had any problems, I have been slowly finding replacement software for everything that I used on windows
Try out krita, rawtherapee, darktable, for photoshop stuffs, depending on what you need.
The Adobe stuff always held me back before but I finally just started messing with linux and trying stuff out. I don’t need photoshop for professional use so I was fine spending the time trying to find alternatives for what I needed
