Description of the Problem, or Question?
Depending on the brush used, normal functioning can be expected, or very light lines, or sometimes none at all. It should be noted that the tablet developers are committed to engaging the Linux community and have a driver in beta. They have been notified of these issues and will work on them when possible. Many of the same problems are present in Krita as well. Further, some of these issues can be temporarily solved in MyPaint by adjusting the pressure sensitivity/gain slider, but that also causes marks to become far too dark. Ideally brushes should work with default settings as they do with Wacom tablets. This is especially apparent when using Deevad’s “paint knife with smudging”. Very frustrating as it is my favourite brush. However, the knife in the “classic” set works just fine. Any idea why this is? I am not too familiar with making my own brushes, so I have no idea what is wrong. Most of the classic set works, along with some airbrushes or ink brushes in other sets, but not much else. As an additional note, I work at large sizes, as my work must be printed: 6500px x 6500px at 300 DPI.
I was not sure if this should be posted in the Developers Area, but I talked with the Support team at XP-Pen, and they seem reasonably open to working with other devs in the Linux community. If someone here in charge of development could reach out to them it may be worthwhile.

Please Tell Us How to Reproduce the Problem in Steps.
I simply selected the “paint knife with smudging” in set #2 and began to draw. No marks showed regardless of pressure applied. This happened with a number of other brushes across different sets. Setting the Gain slider to maximum caused marks to appear, but degraded the quality of what I wanted to achieve significantly, as lines would alternate between light and very dark. Some brushes worked as intended with default settings, but not very many.
