Hi rysen_spark ,
Thank you for your response, we would suggest to uninstall the Wacom drivers as this could have caused glitches on the Surface pen drivers on the Surface Studio.
Also, we recommend to try installing the latest firmware for the Surface Studio 2, through this link.
Before downloading this, please type in winver on the Search tab and take note of the OS Build. Download the closest OS Build on the download option shown on the link above. Once downloaded, please do a restart on the Surface Studio.
Please keep us updated on the results. We look forward for your response.
Regards,
