I seem to have the same problem. I have a HP EliteBook 840 G1 with two external dell monitors (one horizontal and one vertical - rotated counter clockwise - although I don't think that has anything to do with it since I tried to set them all horizontal and the coursors were still doubled).
The "main" cursor is correctly aligned and the "shadow" cursor is the arrow one rotated 90deg counter clockwise. The shadow cursor dissapears once the monitor are disconnected (they are connected through a docking station - the landscape one using VGA and the vertical one using HDMI). Also, the shadow cursor doesn't show on the middle (vertical, connected through HDMI) monitor.

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.
