I am having the same problem described by Cd-MaN on Ubuntu 14.10.  I
have three monitors connected to hdmi, vga, and dvi.  The center monitor
is oriented vertically (rotated 90 degrees).

Occasionally, on the two side monitors (which are conventionally
oriented) the mouse pointer will be duplicated and rotated 90 degrees.
Moving the mouse into the center (vertical) montor, the pointer goes
back to normal, moving it back to the side monitors reproduces the
additional rotated pointer.

I can usually make this go away by opening a terminal, putting my mouse
cursor in the terminal window, and typing exit.

Title:
  Mouse cursor duplicated in dual screen setup

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  I have attached a external monitor to my laptop. When I my the mouse
  from the primary display (my laptop screen) to the secondary display
  (external monitor), the mouse cursor image gets duplicated. On the
  primary screen it freezes its last location (so moving the mouse more
  quickly, makes sure that the mouse image is clearly visible) and on
  the secondary screen it keeps on performing as it should. When I move
  the mouse back to the primary screen, the duplicated mouse image
  disappears and everything works like normal again. When the
  duplication is 'active' the frozen mouse, still changes it's image
  (pointing finger, 'text thingy', resizing arrows, etc.) when my mouse
  on the secondary screen is hovering over elements that makes the image
  change. Since Ubuntu 12.10 I use the xserver-xorg-video-radeon
  package, as fglrx does not support my ATI video card (HD 3650)
  anymore. So I do not know whether the problem is also existing
  pre-12.10. This is not reproducible in the live environment of 13.10
  and 14.04, but is in the installed ones.
