The stylus pressure for the paintbrush tool in the touch workspace on a Microsoft Surface seems to work occasionally but not always. The Surface Pen is connected (Bluetooth), I can get stylus pressure to work sometimes and not others. Sometimes in the same session! Or if I flip to the regular desktop workspace it'll work occasionally. I cannot figure out what the key ingredient is. It seems very random. I can also get it to recognize pressure if I enable "constrain drawing 45deg" but not if I disable it. How does that make sense? Must be a bug. Please address asap!
