Hi ALBERTO! Thanks for the details.
Do you have any of these installed?
- Logi Options+ / Logitech G Hub
- Razer Synapse
- Corsair iCUE
- Microsoft Mouse and Keyboard Center
If yes, open that program look for a setting called: Scroll Speed, Lines per scroll, or Scrolling rate
Set it to “1 line” or “Use OS default”.
Restart Windows.
Best regards,
Kimberly
