Title:
[modeset] Screen tearing when using multiple monitors
Status in X.Org X server:
New
Status in xorg-server package in Ubuntu:
Triaged
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.
