When using my drawing tablet (wacom bamboo fun) in affinity designer to draw freehand curves, the program bugs and creates hundreds of additional lines spontaneously. This problem began today, but is exclusive to Affinity Designer (inkscape, blender, and other tools work fine), and is the same when trying my spare pen. I've attached an image of an attempted horizontal line with the pencil tool to demonstrate the issue. This unfortunately renders the program unusable for my purposes.
before today the tablet worked well within the artboard, but was mysteriously unable to interact with the interface to select tools.
Has anybody experienced a similar issue, and is there a solution? I'm hesitant to replace the hardware when it still works with all the other software I own, as I'm not sure this would resolve the issue.
