The laptop itself is closed (internal display is not used). In a gnome xorg session, there is severe tearing on parts of the screen when dragging windows or scrolling content. Under a wayland session there is no screen tearing, but I have keyboard key repetition problems which make this mostly unusable day- to-day (https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1849405). I can supply short phone videos of tearing occurring on the screens if required.
