Viewport "jumps" when I place objects near the edge

[gregmaletic]

Attached is a video that shows several moments when I drag a shape near the edge of the viewport, and it jumps. Resulting in me placing the object in the wrong location.

How do I turn this off?

Thanks.

I should add: turns out it doesn't have to be near the edge. The "jump" can happen no matter where I'm dragging in the viewport.
