It seems like you are experiencing an issue with your mouse pointer flickering and resetting its position on your Dell Precision 5530 running Windows 11. Here are some steps you can try to resolve the issue:
- Update Drivers: Ensure that all your device drivers, especially the graphics and mouse drivers, are up to date. You can check for updates in Device Manager.
- Check Display Settings: Since the issue goes away when using "second screen only" mode, it may be related to the display settings. Try adjusting the resolution or refresh rate of your display in the settings.
- Disable Touch Features: Since you mentioned that you have a touchscreen, ensure that the touch input is completely disabled. Sometimes, touch inputs can interfere with mouse movements.
- Test Different Cables/Ports: If you are using an external monitor, try using a different HDMI cable or port to see if that resolves the issue.
- Boot in Safe Mode: Boot your laptop in Safe Mode to see if the issue persists. This can help identify if a third-party application is causing the problem.
- Check for Windows Updates: Ensure that your Windows is fully updated, as updates can often resolve hardware compatibility issues.
If the problem continues after trying these steps, it may be worth reaching out to Dell support for further assistance, as it could be a hardware-related issue.
