Apple pencil zig zag, grid Drawing

Well, I’ve been having a lot of frustrations with my Apple Pencil and or tablet. I have an Apple Pencil 2 and a iPad Air 5th gen. I dont have a screen protector on or a cover. When I draw in any app that supports Apple Pencil drawing, then it just draws squiggly lines. This only occurs when I draw diagonally, not horizontal or vertically. I tried to draw with my finger in all directions, but it was like nothing was the matter. I did try to switch pen tips, but nothing had changed at all..

The backstory to when this started was after i got my iPad’s screen fixed. I paid 381$ for the reparation (I thought maybe this info could help knowing if the tablet repair was too cheap or something hahah)

After I got the reparation done, then I noticed some changes to the tablet. Most notably, I could sharply feel that there was something about the screen placement. It was placed a few millimeters below the metal border. So it didn’t have a soft edge like it used to. I don’t know if this helps, but it just felt a little sketchy and weird to me.

All in all I just want some insight about this problem😆 I have been very afraid of needing to get it repaired yet again, mostly cause of the costs. But maybe there’s just a little spec of light, that it can be fixed or calibrated in some way😂

i have some test pics from both the notes app and procreate:
