my pen cursor (i use a Huion Kamvas 20 drawing monitor) suddenly became offset only in Sketchbook (it works in other drawing programs, i tested to make sure) and i don't know how to fix the issue. i tried uninstalling and reinstalling sketchbook and re-calibrating the drawing monitor but it didn't fix it. I've been using sketchbook for 8 months and have never had an issue until now.
