Draw Free bug

When I assign a Drag > Draw Free > line width 15 action to a graphic element, and use my Sony Vaio touch monitor to test it, the lines shoot off on their own accord away from my finger. So it doesn't accurately follow my finger when touching the monitor screen.  I would like this behavior to be more accurate as I want to use to facilitate tracing behavior.  See screenshot below.  If there is a better way to simulate tracing behavior, please advise.  Thanks.
