Hi, Chaolion!
Thanks for reaching out to Microsoft Community and posting your concerns. We are sorry to learn you have issues with your Surface Pro 4 when using your pen on Clip Studio Paint. Thanks for taking the time to let us know about this and allowing us to help you out. May we know if the same thing happens in other apps like the default Paint app on Windows or Microsoft Edge when you try to write? In the meantime, kindly perform the following steps to troubleshoot general issues that may be encountered on the device:
· Check for Windows Update:
Go to Settings > Update & Security > Windows Update > Check for Updates
Please restart your device to apply the updates.
· Run Surface Diagnostic Toolkit and make sure to complete the tasks.
· Force shutdown the device and restart.
- Press and hold the power button until the screen turns off (about 10 seconds), then release the power button.
- Press and release the power button to turn your Surface back on. You should see the Surface logo.
If that doesn't work, use this two-button shutdown process to make sure your Surface turns off completely:
- Press and hold the power button on your Surface until the screen turns off (about 30 seconds), then release it.
- Press and hold the volume-up button and the power button at the same time until the screen turns off (about 15 seconds), then release both.
The screen may flash the Surface logo, but continue holding the buttons down for at least 15 seconds. 3. After you release the buttons, wait 10 seconds. 4. Press and release the power button to turn your Surface back on. You should see the Surface logo.
If this answers your question, please let our Community know by marking this post as an answer. Otherwise, don't hesitate to respond to this thread if there’s anything else that needs to be addressed.
Kind regards,
Janette_Z
