Detect unwanted cursor movement when your mouse is stationary
Sensor drift can affect precision in games and design work
Unwanted cursor movement when the mouse is not being moved
Dirty sensor, reflective surface, sensor malfunction, or interference
Clean sensor, use proper mousepad, update drivers, check surface
Click "Start Test" and keep your mouse perfectly still
Mouse drift occurs when your cursor moves on screen even though the mouse is completely stationary. This is typically caused by:
Note: Some minimal drift (1-2 pixels) can be normal due to micro-vibrations in the environment or sensor sensitivity. Only consistent or large amounts of drift indicate a problem.
