Drag and drop smoothly question

Hello, how can I ensure that when moving an element (drag and drop on the document), the green line doesn't cause a jump and the line moves smoothly and more easily?

My request concern the line limegreen in vvvv draghtml

For example, in this competitor's project, the movement of an element doesn't cause jumps and moves smoothly.
