New “typing in full screen” pop up keeps getting in the way when I’m not even typing, how do I turn it off?

Everything was fine until I updated my (6th gen) iPad to iOS 15.3 this week. I play games on this website and putting it in full screen makes it easier, but now whenever I put it in the full screen every couple of clicks I get a pop-up that says you are trying to type in full screen, stay in full screen or exit. And I’m not even typing. I am clicking the tiles in my game. I’ve closed full screen to check and see if my keyboard was open and it wasn’t, there’s no text bar where I was previously typing. How do I turn off this pop-up, it keeps getting in the way of my game and it’s un-useful
