Mouse Sensitivity 1.14.3

After loading up the new updated version, I noticed my mouse movements moving much faster than normal. They were and have been at 100% sensitivity. I have been using an MX Anywhere 2S wireless mouse from Logitech, and it has been up to date. After lowering the sensitivity to 10% and slowing working back up, I also noticed that the movements of what I was doing were not the same on screen. At times, the crosshairs would jump sporadically, the POV seemed to be increased in a closer environment to other objects, and it has made the experience unplayable with this headache of unpredictability. Playing on Hardcore on a Windows 10 laptop, I do not intend to continue playing till I know this has been addressed for the sake of my created world.
