iPad Pro 12.9 3rd generation

When I am playing games on my IPad Pro there are places on the screen that I have to tap a few times for the game to register. There is nothing wrong with the glass of my iPad so I’m confused as to why this problem seems to happen all the time.

I tried looking for answers, but they all seemed to be about the glass being broken & replaced. Which isn’t exactly my problem. It’s more like the “guts” underneath the glass seems like my problem.
