My mouse is stuttering or skipping on the glass pad / loss of tracking

If your cursor is jittering, skipping, or losing tracking on a WALLHACK pad, work through these checks in order. The first three resolve the vast majority of cases.

Symptoms

• Cursor jumps or freezes mid-motion
• Tracking feels inconsistent at certain pad locations
• Spin-out at fast flicks
• Sensor briefly loses contact, then resumes

Cause

Glass surfaces need both a clean sensor and a clean surface to perform consistently. The most common cause is buildup; often invisible to the eye - on either the pad or the mouse sensor lens. Less commonly: worn skates, sensor incompatibility, or wireless interference.

Solution

1. Wipe the pad

Use a dry microfiber to clear dust and finger oils. If it's been a while since a wet clean, follow our cleaning guide.

2. Clean the sensor lens

A speck of dust on the sensor causes more stutter than a dirty pad ever will. See "How do I clean my mouse sensor?"

3. Inspect your skates

Under a bright light, check for cracks, lifted edges, or worn-through PTFE. If the skates look damaged, replace them. See "How do I remove and replace the skates on my mouse?"

4. Check sensor compatibility

WALLHACK glass works with virtually every modern optical sensor (PixArt 3360, 3370, 3389, 3395, 3950 and their derivatives). Older or budget sensors (PMW3320, A3050 and similar) can struggle on glass. If you're on a vintage or low-cost mouse, glass may not be the variable you can fix.

 5. Lift-Off Distance Settings
 There have been instances of setting low LOD within your mouse settings to cause issues with glass surfaces. Try setting your mouse’s LOD to Medium or High within your mouse driver’s settings, software. Additionally, if your mouse has a “Gaming Surface Mode”, try disabling it and see if it solves the problem.

6. Wireless interference

If you're on a wireless mouse, move the receiver closer to the mouse, within line of sight where possible. USB 3.0 hubs and ports can generate interference; try a USB 2.0 port or a USB extension cable to reposition the receiver.

7. Polling rate too high for the system

Running 8000 Hz polling can overwhelm older CPUs or USB buses. Try dropping to 2000 Hz or 1000 Hz and see if the stutter resolves. 

Prevention

• Wipe the pad before each session
• Clean the sensor lens every 2-4 weeks
• Try different mouse settings
• Replace skates when you see visible wear
• Keep food and dust away from the desk
