Thank you for posting your question in the Microsoft Q&A forum
Regarding your issue, this usually happens when Windows is receiving conflicting input signals, such as two pointing devices being active at the same time (for example, a USB/Bluetooth mouse plus a touchpad or touchscreen), or when there’s a driver or software glitch causing the cursor to jump or blink.
Here are a few steps you can try:
- Disable the Touchscreen
- Right-click the Start button and select Device Manager.
- Expand Human Interface Devices.
- Right-click HID-compliant touch pad and select Properties > Driver > Disable device.
- Check if the second pointer vanishes.
- Check for Inputs in Settings
- Go to Settings > Bluetooth & Devices > Mouse > Additional Mouse Settings.
- Under the Pointer Options tab, ensure Display pointer trails is turned OFF. If this is on and glitching, it can look like multiple pointers are "stuck" on screen.
- Reinstall Graphics and Mouse Drivers
- In Device Manager, expand Mice and other pointing devices.
- Right-click your mouse and select Uninstall device, then restart your computer. Windows will automatically reinstall a fresh driver.
- Do the same for your Display adapters if the blinking persists.
Hopefully it will help work with your issue and if you have any other questions or need further assistance, feel free to ask.
