I've been experiencing a strange issue with my Viper V4 Pro and I'm wondering if anyone else has seen something similar.
The problem
After moving the mouse and then leaving it completely still, there seems to be a 5-10% chance that the mouse enters some kind of bugged state.
Once it happens:
- The wireless dongle never goes to sleep.
- Windows thinks there is constant activity, so the monitor never turns off automatically.
- If I'm watching a fullscreen video with the cursor hidden, the cursor pops up every few seconds.
- The issue persists indefinitely until I move the mouse again.
Interestingly, if the bug does NOT occur after I stop moving the mouse, everything works normally and the mouse can stay idle for hours without triggering it.
Reproduction pattern
Every "move → stop" cycle is basically a new attempt:
- Move the mouse.
- Stop moving.
- About 90-95% of the time everything is normal.
- About 5-10% of the time the mouse enters this weird state.
- Once it enters the state, it remains there forever until I move the mouse again.
So it doesn't randomly start while sitting idle. It only seems to happen immediately after movement stops.
What I observe
The behavior makes me suspect that the sensor or firmware might be continuously reporting tiny ΔX/ΔY values, causing Windows to think there is constant mouse activity.
The cursor itself doesn't visibly drift, but:
- Monitor sleep is prevented.
- The dongle stays awake.
- Hidden cursors in fullscreen videos periodically reappear.
