Personally I haven’t. While Linux is imperfect, choosing the right distro makes the rest of the experience straightforward. And with it’s whole complexity, I find Linux more user friendly than Windows. Even driver issues, broken shadow file ownership and KDE specifics only made me more confident about my choice to use Linux after I solved everything.
fortunately I’ve had no trouble with Krita for drawing or animation, and the calibration thing is just a minor nitpick. The tablet otherwise works perfectly I would just prefer if the cursor was very slightly to the left of the pen nib instead of directly underneath it so i could see what I’m doing better.
