If your mouse scroll wheel is exhibiting jittery or inconsistent behavior, it's possible that the issue lies with the encoder. 

This is often caused by the accumulation of dust, dirt, or fluids within the encoder, which disrupts its signal. 

In most cases, you can resolve this problem by cleaning your mouse.

One effective method to remove dust from the encoder is to rapidly roll the scroll wheel on a flat surface until the dust is cleared. If this doesn't work, you can also attempt cleaning the encoder with compressed air.

If these cleaning methods fail to rectify the issue, it's probable that the encoder is defective and needs to be replaced with a new one.
