If an application does not handle touch input "natively" (processing WM_POINTER messages), Windows moves the mouse cursor to the touched location. This leads to "jumps" when using vacs on a touch screen, requiring users to move their mouse back to the original position after each touch, which is especially annoying when used on a secondary monitor.
