Middle section of ipad glitching

Whenever I write something in the middle section of my ipad using my apple pencil, it would glitch. It's really frustrating cause it wasn't like this just a couple of days ago. I tried changing the pencil, but the problem persisted, so I figured that the problem is with the ipad itself. I have even updated my ipad to version 15.3 thinking that apple would have resolved this problem, but no.
