I have not had the use case in question on older versions so I don't know.
If you want me to I can install several older versions of Ubuntu later and see
if the problem occurs in those versions as well.

Title:
Mouse flickering and mouse trails with DL screen attached
Status in xorg package in Ubuntu:
New
Bug description:
When attaching a screen on a DisplayLink device, the cursor will
flicker on all non-DisplayLink screens. Additionally, the cursor will
leave trails over various UI elements that update as the cursor passes
(such as buttons, menus, progress bars, etc.)
The issue occurs only when a DisplayLink device is attached and
driving a display. However, DisplayLink told me the issue is not
specific to their hardware, and to make a bug report here.
