Pressure sensitivity from Surface Pen simply doesn't register in Blender. Works in other apps like Sketchbook Pro and various Windows 10 Ink apps like Sketch, OneNote, Sticky notes

@Daniel Martinez Lara (pepeland) iirc, you are using a surface tablet with Blender? are you aware of anything special about that topic?

Otherwise I guess we'll need a dev with that hardware to investigate and fix (iirc microsoft changed some stuff re tablet/pen access some times ago, though I thought we had that integrated…).

Yes, I use Blender in surface book 2 with same issue and after instaling Wintab_x64_1.0.0.20 driver the pressure works (yay!) but Blender have some
problems manage this kind of pen devices, like this one https://developer.blender.org/T55589 the problem is that pen event is not received for the first movements of the pen and only after a while.
this task appear closed but still happening.

Installing Wintab_x64_1.0.0.20 driver solved the issue for me as well on Surface Laptop just now. Thanks @Daniel Martinez Lara (pepeland)
