I just recently bought a Wacom smart pen (Samsung version) and the tablet works fine with it, that is as long as I stay within the central area. Every corner but the bottom right one doesn’t respond at all, and the movement gets considerably less fluid by the edges. I ran a 120 point calibration and the effect is less noticeable, but far from solved. I can still not use the edges because they act as if they had literally only 3-ish levels so it’s really hard to scroll. I suspect a broken digitalizer at the top left corner, but I’m not sure.
I also reinstalled Windows 10 and the problem persists with and without the Wacom drivers.
