Mouse sensitivity issue

So before the RenderDragon update, my mouse sensitivity was perfect, but after the update, my mouse sensitivity became heavy, I tried to go to the mouse & keyboard to change my sensitivity, but no result, any solution? ]

Since it doesn't allow me to attach the video because of how large its size, here is it https://www.youtube.com/watch?v=0Mr1369kacs
