Two mouse pointers with external display.

[M Willis Monroe]

Sometimes when switching the cursor between displays the mouse pointer will duplicate itself on the main display but the second cursor will appear below the primary cursor and rotated 90° counter-clockwise (the external display is also rotated 90° counter-clockwise).

This bug will go away on reboot, or sometimes by itself.

Attached is a photo of the effect.
