IOS Overlay Glitch, Does this Happen on your Game?

So I have spent hours both researching on the internet and experimenting in game with this overlay glitch.

I have been playing Digimon World on the pcsx ReArmed, and all the save and load states work fine for the first hour but then whenever I try to load one of my states after the first hour the buttons freeze. For example, I might have three consecutive save states that load fine followed by three that will freeze when loaded. If I load a frozen state, then the game will continue to play but none of the buttons work. If I hold a button down when I load the state, then it is like I am holding that button continually, and I can’t pressing anything else (so my avatar will continually run in that direction). If I start over then I can then use the same save state over again for a little while until it eventually starts freezing. I have researched and tried to set all of my relative permissions correctly. I tried playing several different ROMS of this game. I have not noticed this glitch on any of the other games I have played. This glitch renders my game completely unplayable unless I want to finish it all in one sitting.

Have you seen this glitch on any other games? What could be causing it and how can I fix it?
