What is mouse drift?
Mouse drift is when the cursor creeps, jitters or slides across the screen while nobody is touching the mouse. It’s distracting when you work, and in games it can throw off your aim.
How the test works
- Place your mouse on its usual surface and press Start.
- Let go during the 3-second countdown and keep your hands off the desk.
- For 15 seconds, the test records every movement your mouse reports.
If the cursor moves over the test area, a red dot shows where. At the end you get the number of movement events and the total distance.
Common causes, and fixes
| Cause | Fix |
|---|---|
| Hair or dust on the sensor | Blow out the sensor opening, and wipe it gently with a dry cotton swab |
| Glass, glossy or patterned surface | Use a plain cloth mouse pad |
| Uneven or worn mouse pad | Replace it. Frayed spots can confuse the sensor |
| Desk vibration (fans, speakers, typing) | Run the test again with everything still |
| Wireless interference | Move the receiver closer and away from USB 3 ports and Wi-Fi routers |
| Low battery | Replace or charge it. Weak power can make sensors noisy |
| Sensor hardware fault | If drift happens on every surface after cleaning, the sensor may be failing |
Laptops
On laptops, phantom cursor movement often comes from the touchpad, not the mouse. A palm resting on it, moisture, or a swollen battery pressing from underneath can all cause it. Try disabling the touchpad and running the test again.
Next, check that the sensor reports smoothly with the polling rate test.
Frequently asked questions
Can mouse drift be fixed?
Usually. Most drift comes from dirt on the sensor, a reflective or uneven surface, or a wireless interference problem. All of these are easy to fix. Hardware sensor faults are rarer.
Is this a controller stick drift test?
No. This test is for computer mice. Controller drift comes from analog stick wear and needs a gamepad tester.
