Logitech G Pro sensor tracking issue/bug ?

So I just bought a G Pro from a friend, and the mouse is fresh new.

However, it is impossible to use the mouse due to some tracking/sensor bug that I have never seen before: https://youtu.be/ZHM0LH2yDYw

While swiping from left to right (or vice-versa), the sensor starts flickering/jumping pixels or even not moving at all.

I have tested this with a pad and without a pad. I also own a G403 and the G403 is just fine with or without the pad.

Has anyone ever seen this before ?
