User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:69.0) Gecko/20100101 Firefox/69.0

Steps to reproduce:

  • Windows 10, Wacom Tablet (tested with Bamboo and Intuos 4)
  • Open: (similar behavior is to be observed on almost all drawing sites, or sites that use drawing widgets)
  • click "init with mouse-events"
  • draw a smiley with the pen

Actual results:

  • the drawing is all messed up

Expected results:

  • you should see a smileyface

It works when you press "init with pointer-events" and then draw, or use another browser.

This breaks almost all drawing sites. They can't really switch over to pointer events, because Firefox has a lot of bugs with that too. It used to be great in the past, but currenty Firefox is very broken for stylus users.
