Short description of error
If I tap on the Blender window with my tablet pen, the pen, pen buttons, and tablet buttons all stop responding until I use my physical mouse to click outside of the window. Tapping the Blender window will once again cause it to stop responding. and the cycle repeats.
I can still use any other windows like my web browser or windows settings menus, but once I tap on Blender it locks up
I can even hover over Blender with my pen and it'll track my mouse cursor, but the instant I actually click/tap on it I lose all control.
TABLET: Huion Kamvas Pro 13 (latest drivers)

Step 1. Have a Huion Kamvas 13 display tablet
Step 2. Open Blender 2.80
