Windows 10: Cursor doesn't move when mouse is moved slowly, but moves when moved quickly

My mouse doesn't work when I move it slowly when I intend to move my cursor slightly, but it only moves when I move the mouse faster. I have this problem in 2/4 of the mouses I use, both of which are new, and I think it might be a Windows problem.

Cursor moving down the page without any mouse input

I thought I was having an issue with my mouse, but after conducting troubleshooting steps from the manufacturer, it could be another problem. Recently my cursor started moving down the page without any input from my mouse. When I disconnected the mouse from the computer the cursor would still move slowly down the page. What could be the issue?

Keyboard-controller :

Hi, I want to move cursor controller more slowly....

Browse your text with the cursor controller
The cursor controller is the circle near the bottom of your screen.

1. MOVE FAST

Press and hold the cursor controller and then flick it in the direction you want to go to move from character to character or line by line.

2. MOVE SLOWLY

Or scroll through the text more ´+++slowly+++ by pressing it and then dragging your finger in the direction you’d like the cursor to move.



I CAN NOT REPRODUCE MORE SLOWLY, it does not work on me....


What is the exact diference between 1 and 2...?
