The two monitors are 2560x1440, with no scaling. But I do use a 1.25
font scaling factor in gnome-tweaks.
I am using the ubuntu-x-swat ppa, which was an attempt to resolve some previous
graphics issues, but I can try removing this again if you'd like me to test?

Title:
Screen tearing in xorg gnome session on Latitude 7480 with WD19TB
Thunderbolt dock
Status in mutter package in Ubuntu:
New
Bug description:
I have the WD19TB Thunderbolt 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
(https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1849405).
I can supply short phone videos of tearing occurring on the screens if
required.
