Description
Mouse Scroll Test is a browser-based diagnostic for mouse scroll wheel behavior. It captures every scroll event your mouse fires — direction, magnitude, timestamp — and visualizes them so you can quickly spot the symptoms of a failing wheel: skipped notches, ghost reverse-scrolls, double-counting, or jittery delta values.Useful when troubleshooting an aging mouse before deciding whether to clean the encoder, replace the mouse, or rule out a software / driver issue. Also handy for confirming whether a fresh mouse is genuinely defective during the return window.
