Mouse Jitter Test
Confirm cursor jitter locally before changing DPI, cleaning the sensor, or replacing the mouse.
Check path
Keep the mouse still and watch whether movement events continue.
Clean the sensor lens and retest on a plain surface.
Move the cable or receiver to see whether jitter changes.
Buy later
Clean first when dust or hair near the sensor changes the result.
Use another surface when jitter disappears on a control pad.
Replace only when idle jitter follows the mouse across surfaces and ports.
Repair picks
A clean, consistent pad can fix many tracking symptoms before you blame the sensor.

FAQs
How do I test mouse jitter? +
Hold the mouse still and watch for movement events or cursor shake. Then retest after cleaning the sensor and changing surfaces.
Can a dirty sensor cause mouse jitter? +
Yes. Dust, hair, and reflective debris near the sensor can create noisy tracking. Cleaning is the first fix before replacing hardware.
Can wireless interference cause jitter? +
Yes. Move the receiver closer, avoid crowded USB ports, and compare wired mode where possible. If the jitter disappears, the mouse itself may be fine.
