When moving the mouse pointer from screen 1 to screen 2, the pointer is not disabled on screen 1. It remains visible at its last position on screen 1 while a second cursor is now moving on screen 2. The same happens when moving from screen 2 back to screen 1. The mouse pointer on screen 1 will move while the pointer on screen 2 remains visible at its last position.
BTW, this bug also affects fglrx.
