Mouse eratic motion issues

I am having erratic mouse tracking issues. In addition to the erratic (jumping) issue I reported yesterday, I still cannot make the mouse sensitivity level useful. I did try the suggestion for changing the movement and even at 1/8 it still zooms out of sight with the smallest motion. I did determine that it’s not my mouse (wired Hilarly F300) by connecting my Microsoft Bluetooth mouse and the results were the same. Both of these mice work well (normal motion) under windows 10. Weird!
