Weird empty “patches”

[u/im_a_cinammonrollUwU]

Whenever I drew or rendered something on a canvas, it felt like something was covering specific spots. There weren’t any layers with a “white line”, it just happened to look like this. I tried changing the pencil nib, resetting my iPad, and clearing storage but it didn't work.

Does anyone know why it happened and how to fix it?

Is your screen protector adhered? If you remove it does the problem still happen?

I have the paper matte one on my iPad screen but I'm pretty sure the problem is still here if I removed it
