Most often, the mouse encoder causes your mouse scroll to be unstable and jumpy.

In some cases, the scroll wheel itself is to blame.

Alternatively, you might unmount the scroll wheel directly without unmounting the circuit.

Then, unplug any other connections, unscrew any screws, and take out the scroll wheel.

To do so, press against the D-shaped metal spring inside the encoder box and remove the metal cover.

Most of the time, this is what causes a jumpy scroll wheel.
