I am having the same issue.  When I push the middle mouse button to activate the automatic scrolling, I get a small area just below the cursor that does not refresh.  As I move the mouse up or down to begin scrolling, the area below the cursor captures whatever is directly below it and carries it with the cursor.

When I click the left mouse button to stop scrolling, the small image below the mouse is left on the screen.  I can then roll the middle mouse button/wheel up or down to refresh that small area.
