I’ve installed Pop!OS after getting my Lenovo Ideapad Pro 5 back from the warranty repair. Supposedly they changed the motherboard (which I don’t doubt, it was waiting a week for new parts apparently), but even after that I’m still getting graphical errors and bugs when moving between desktops and other window animations. I know X11 can be a bit buggy at best, so it could just be that on top of the newer SoC.
Could you describe the kind of glitches you are getting?
As a first test (and only as a test) I would try holding space bar during boot, then pressing E while focusing the Pop!_OS option, and removing quiet and splash from the line on the bottom, then pressing enter to boot.
