I have the WD19TB Thubderbolt dock connected to a Dell Latitude 7480 laptop with two external displays. 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 (#1849405).
I can supply short phone videos of tearing occurring on the screens if required.
