iPad screen zoom problem

Within the last couple weeks my iPad does this thing where it "zooms" in a bit and cuts off like 3/4" of the screen out beyond the bezel. Effectively hiding the back button and other controls that exist near the edges of the screen. I can kill the app and it will usually reset to normal size, but then something I haven't figured out yet will zoom it in again. I have checked in setting under the display heading and nothing is toggled on that would cause this as far as I can tell. I updated the ios to 15.2 hoping it would fix the issue but it's still happening. Any ideas of why this is happening or how to adjust settings to avoid it? Btw I use a magic mouse 2 with the iPad most of the day at work in case there may be something about the combo that's causing the malfunction. Thanks!
