Description of problem:

I have three displays connected to a Radeon RX480. One is 3840x2160
(landscape), the other two are 1200x1920 (portrait left and right,
respectively). The 4k display is indexed as the third one in the
Displays panel of the Settings app, and arranged as the rightmost of the
three displays.

After upgrading to Fedora 27, when the mouse pointer is near the left
edge of the 4k display, it also appears on the adjacent 2k display. The
extra pointer is displayed as if the display was in landscape mode, so
it appears rotated relative to the display contents. It seems to be just
a display bug; click events go correctly to items on the 4k display.

Version-Release number of selected component (if applicable):

wayland-1.14.0-1.fc27
gnome-shell-3.26.2-1.fc27

How reproducible:

Always.

Steps to Reproduce:

I haven't tried to reproduce from a fresh config. Hopefully it's
reproducible with a similar config.

If I unplug one of the 2k monitors I can still reproduce if the
remaining 2k monitor is in 'portrait left' but not 'landscape'. So the
issue should be reproducible with two screens.

Any hints on how to debug this?

It also happens to me, I have two monitors and one is on 'Portrait right'.
Any hint on how to debug or provide more information?

Same here with 3 screens on Wayland. 
The second pointer appears on the monitor on the left which is set as portrait. 
All of the 3 screens are set to 1920x1080.

I currently have this problem after a system upgrade from 26 to 27.
I have a triple monitor setup, with the leftmost monitor set to "portrait 
right" (like most people commenting)

My current work around is to align the bottom of my left monitor (in
portrait right) to the bottom of my center monitor (in landscape)

If I align the top, so that there are more pixels below my center
monitor the "ghost" cursor appears. After some testing, I found that
this only happens in "portrait right" and "portrait left" on the left-
most monitor. Adjusting the position and orientation on my right monitor
doesn't have an affect.

As a temporary workaround, selecting "GNOME on Xorg" at login does work
with F27 and the same gnome-shell version.

Bug description:
  When my 2nd Asus (Ancor) display is in portrait mode and is set to be
  to the left of my centered landscape display in extended mode, moving
  the mouse to roughly the left 20% of my landscape display will show a
  mouse cursor on my landcape display AND portrait display at the same
  time.  Oddly moving a window into this area only shows on the
  landscape display.
