As shown in the video, I am able to hover over and click the dragging arrows just fine, but then when I proceed to drag the selection, the model ‘pops’ several studs away (way more than I began to drag with my mouse) and stays that distance away from the dragging handle.
Expected behavior
Ideally, the model needs to stay close where it was when I began to drag with my mouse, and only move proportionately to how far the drag handle has moved.
