Ubuntu 17.10 - portrait monitor showing extra arrow

Question

I recently hooked-up a second monitor to an Nvidia GEFORCE GTX 1060. When I am using my primary monitor, the secondary monitor shows the cursor as well.

My monitor setup:

Left monitor portrait _____ 1200x1920 (secondary)
Right monitor landscape __ 1920x1200 (primary)

with the Ubuntu desktop.

In particular, when my cursor is in the top-left 1/6th of the primary landscape monitor, I see the cursor in the bottom-left 1/6th of my secondary portrait monitor. But, if I am in that same bottom-left 1/6th of the secondary portrait monitor, I do not see it in the primary landscape monitor.

Note: I have already tried using the proprietary and Nouveau open-source driver, and this unfortunately did not solve the issue.

@ravery They don't, but when I was checking this a second ago, if I make the portrait monitor be on the right side of the primary landscape one, then I don't have this problem. Strange. — Janusz, Feb 06 '18 at 17:08
@pomsky Thank for the hint. This seems to have solved the problem. — Janusz, Feb 07 '18 at 09:24
@Janusz Bugs should be reported at launchpad. Try here: https://bugs.launchpad.net/ubuntu/+source/gnome-shell. — pomsky, Feb 07 '18 at 09:42

This seems like a yet-another-issue-with-Wayland.

As a workaround you may switch back to Xorg from the default Wayland session following this Q&A: How do you switch from Wayland back to Xorg in Ubuntu 17.10?
