I'm not sure if this is a bug, but here it goes. About 10 minutes into the game, the screen itself freezes, but the game is still going. I can still hear the sound from the game, but the screen does not show me making that specific sound, such as opening a chest or the sprinting sounds. When I press "Esc", the cursor shows up, but the "exit screen" (with the Back to Game, Quit to Title, etc.) does not appear. I tried to click on the "Quit to Title" tab where the spot should be at, but that doesn't work. I have to manually close Minecraft using the "x" button at the top.
