I use two displays. One has a resolution of 3840x2160, and another one
is to the right of that with a resolution of 1080x1920 in "Portrait
Left" mode. I use "Join Displays" in Settings > Displays.
When I configure this setup using Settings > Displays, my main desktop
ends up being too big, extending to the secondary monitor to the right.
When I move my mouse to the right edge of the secondary screen, the
desktop pans.
When I arrange the secondary monitor to the left of my main display,
this bug does not occur.
Secondary monitor on the right (bug):

The only difference between these two situations is that I dragged the
monitor from the right to the left in Settings > Displays.
