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.
