I found out how to stop and activate the bug.
Universal access:Zoom:on Produce trail
Universal Access:Zoom:off Stop the trail
Not tested on Ubuntu but on Manjaro.
Quite sure it's the same problem on Ubuntu.

Tested again a few times: I confirm that switching to nouveau removes
the mouse trail but slows down the desktop to unworkable.
To clarify #6: It could be that in my first test I did not reboot, although
this is quite unlikely.
I could re-install the OS if you want me to try to replicate this.
Though that contradicts what you said at the top of the bug:
> This happens with proprietary nvidia 440 drivers as well as nouveau on
my GeFOrce GTX 1050 mobile.
Can you please clarify which is true?

Hmm, sounds like we still don't accelerated support for GTX 10 series
(Pascal) chips in nouveau. So that's an inconclusive test. Thanks
though.

Mouse trail is gone with nouveau, but desktop is very very slow in all
three modes XOrg, Gnome Classic, and Ubuntu. I had to switch back to 440
to be able to work.
Switching drivers was only possible via CLI.
The mouse trail is only apparent on the background, not inside
application windows.

Please try switching to nouveau and then log into 'Ubuntu on Wayland'.
Does that avoid the problem?
