Even when drawing a line or picture with a pen or drawing a small dot-like circle, the drawing pen and the screen do not match, and there is a phenomenon of dragging or slowness of not being able to follow the pen. I contacted the pen directly and confirmed that there was no problem. I thought it might be a problem with the Click Studio program, so I deleted it and reinstalled it, but the same problem occurred. I think it would be better to show it as a video rather than a photo, but I don't know how to attach the video, so I'll write it down first. What should I do?
