Screen issues?

Hi just wanted to ask if it's normal to have a screen who looks like there's slashes all over text, what I mean is there's a visible lines everywhere and it looks like a slashes. For context I recently brought my first Iphone and installed privacy tempered. I only noticed it after I installed the tempered glass. I probably used to much force to erase the bubbles so wondering if that is the caused?

Thanks a lot to whoever can answer this. Thanks.
