@Conan_Kudo @davidrevoy indeed, I added support for a bunch of XP-Pen tablets, but none of them was an Artist.
I believe the commit you mentioned is causing the issue. Since you already submitted it upstream, the author will probably look into it and fix it.
If you are willing to test a with me a kernel driver I can add support for your tablet on the UCLogic driver and get it to work with no/minimum configuration. Feel free to ping me and I'll help you.
