Getting graphics artifacting on my 7840HS laptop, even after a motherboard replacement. Is it a driver thing?

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....
