Wacom Intous Pro inpainting problem

Nobody has claimed this yet.

Problem with drawing masks\sketching using Wacom Intuos Pro (PTH-660).
The mask starts to draw, but almost immediately stops and starts moving whole screen. Check video.

Reproduce the issue by drawing an inpainting mask with the Wacom Intuos Pro (PTH-660) in the web UI, using the configuration and version from the report. Trace the mask-drawing and screen-panning input handling; done means strokes continue normally without switching to whole-screen movement.
