Hi gigantkranion,
Thank you for posting in Microsoft Community.
I understand that you'd like to use the Pen on your Surface with clear and clean ink result. I appreciate the effort in performing the troubleshooting methods.
Just want to confirm few questions:
- What type of Surface Pen you're using?
- When you uninstalled the HID drivers, did you uninstall the HID-Compliant Touch Screen and the Intel(R) Precise Touch Device?
- Does it happen to built-in writing apps, like OneNote, Microsoft Word and etc.?
- Does it happens when connected to a charger?
Please also perform the methods below:
- Try to uninstall the display adapter. Go to device manager > expand the display adapter > right-click then choose uninstall > restart the device.
- Adjust the Pen writing sensitivity. Go to search > Search for Surface App > on the Left side, find the pen logo > then adjust the pressure.
- If you are using a Surface Pen, try to reseat the Pen Tip.
- Install the drivers manually.
- Check the specific OS build of your Windows Settings> System> About.
- Download the driver and firmware for Surface, choose Surface Pro 7 and click download on the next page.
- Please choose the .msi file that matches your current OS Build and click Next.
- After the download, runand installthe .msi then Restart the Surface Device.
Let me know how this goes.
