At the entrance, a strange bug appears, which can not be removed in any way. 

After the app download, everything is fine. If you go to it once, everything works. But when you enter the second time, a strange bug appears - inscriptions that can not be removed in any way. I reinstalled Minecraft, but it's useless. Everything is repeated again and again.

This bug consists of letters with the names of the keys that appear on the type "my world", "my game", "store" and so on. It appears in full screen and there is no way to remove it, except to reinstall it, but even this does not help.
