UI glitchs and menu glitchs

There is a bunch of User interface bugs atleast 5 I have noticed. When your in a world and go to the xbox home then go back to minecraft(bedrock) there will be a minecraft logo bigger than normal on the bottom right. When you open chest it has a tiny delay in loading the menu for chest the settings and opening creative menu. Also when starting a world the map will have the black,purple texture. When loading up worlds it will freeze and have lower frames. Especially exiting worlds as well and loading your custom characters. In a nutshell the game menu and UI isnt loading as fast before the recent updates. This is  not in the 0.16.0 beta this is in the game already.
