[not a Bug] Duplicating and moving moves in wrong direction for short time

[Nova]

This one is a bit hard to describe, but I hope it makes sense.

On my machine (i7-5820k @ 3.30 GHz, 16 gb, GTX 970), when I duplicate several objects (8 cubes in this case) there's a small delay in the duplication, where if I move my mouse immediately as I'm duplicating, the duplicated objects get moved in the opposite direction of my mouse movement. So if I'm moving my mouse on the +Z axis, it moves along the -Z axis until i stop moving the mouse, whereafter it then moves normally again.

I'm using duplicate free and I have it tied to Shift-C (If that should be relevant).

Nova, that happens only in Z axis, right?

I checked and it uses to work that way (oldest installed version I have - 1.3.1)

It just strange, but the "logic" behind is:
- mouse moved left will move the object in the positive direction;
- mouse moved righ will move the object in the negative direction;
