This problem has existed for some time and I have seen it on 18.04, 19.04 and 19.10 when using the X Org drivers. When using the Wayland drivers on 19.04 the problem went away (The configuration I am using now).
The below link shows a picture of a laggy/tearing screen when you move a window from left to right. (I copied this from the website mentioned above)

Given that the Laptop screen and HDMI port work fine I am assuming this is an issue with the Display link driver.
I am very keen to resolve this issue and am willing to promptly provide any information required to debug this. I am technically minded and have reasonable Linux skills.
Please let me know the next steps.
Regards Ralph.
