moving / distorted pixels glitch??

ok so im having this problem where basically, sometimes when im drawing, the pixels on one side will glitch and move a few spaces, and leave this weird distorted looking lineart. sometimes its only minor like one pixel, and sometimes its so bad it makes the entire drawing look terrible. its super annoying because I tend to draw the lineart, copy it, then color and paste the lineart back over, resulting in the lineart being extremely thick or even overlapping on one part of the drawing.

is anyone else having this problem and/or know how to fix it?? I looked it up and couldn't find anything so am I the only one having this?? also iirc, i might be wrong but i think it only happens on my ipad, not phone (also crappy since thats what i mainly use)
