Bug Description
Binary package hint: xserver-
The cursor motion on a trackpad is derived from the distance of the current touch location from the previous touch location. When the number of touches on the trackpad changes, the touch location may jump causing a cursor jump. This has been remedied by the following commit:
However, the multitouch patches added to synaptics cause the change in the number of fingers to be reported one frame after the actual change. This allows a cursor jump to occur.
