When connecting a mouse to my iPad sometimes right clicking closes the game. This is due to when I position the mouse on the bottom of the screen over the little bar. Normally right clicking this exits an app so its not a big surprise it does this except it doesn’t allow me to play until I move it. My suggestion would be to reset it every time you open/close your inventory and have it set to the center because I think that’s what it does on Windows although I’m not sure if this is unfixable as this isn’t technically Mojang’s fault.

Steps to Reproduce:

1. Open your inventory
2. Position the circle on the bar at the bottom of the screen
3. Close your inventory then right click
