Screen setup.

I'm using KDE Neon.  I have a dual monitor setup.  My left monitor is
vertically mounted (1920x1080), and my right monitor is horizontally mounted
(1920x1080) and is the primary.  When I connect with KRFB (using my phone or
outside work computer), then it shows the primary monitor... I can live with
not being able to view the left monitor... However, on the client VNC session
my mouse position does not match the position on the host computer.  The mouse
position on the client is about a half screen to the right of where it's
actually hovering/clicking on the host machine. (eg. Clicking/hovering on the
far right of the client's remote screen generates a click/hover around the
centre of the host machine.)   Switching between screen capture modes of "xcb"
or "pw" doesn't seem to help.

I used to get around this by showing both screens using a third screen capture
mode ("qt0" or something like that), but it's been unavailable since some KDE
Neon upgrade.

SUMMARY
Mouse position doesn't match on client and host when using multiple monitors.

STEPS TO REPRODUCE
1. Set up your screens as I have described (or see attached image)
2. Connect.
3. 

OBSERVED RESULT
Mouse position doesn't match between host and client (see above)

EXPECTED RESULT
Mouse position matches between host and client.
