By default, a computer mouse scrolls down three lines at a time when using Windows 11. Therefore, the active app window goes three lines lower each time you rotate the mouse scroll wheel downward. When you use a Windows 11 laptop with a touchpad, scrolling on the touchpad reverses the direction. Dragging down two fingers on the touchpad scrolls the active window upwards. If you want to change this behavior, you can set Windows 11 to invert the scrolling direction for your mouse or touchpad. https://www.digitalcitizen.life/change-mouse-touchpad-scroll-direction-windows-11/?utm_source=whatsapp
