When i open minecraft everything looks normal, but whenever I enter a world (every world I own) it starts lagging. after like a minute or two it starts freezing for a really long time and every button on the controller doesn't work anymore. after like 10 minute it goes on normally but then after a few seconds this happens again!

Quello che mi aspettavo che accadesse era...: 

it should be normal

Quello che è realmente accaduto è stato...:
the game freeze and the buttons on the controller doesn't work exept for the home button

Passaggi da riprodurre:
1. open minecraft and select a world

2. start playing (build something, go fishing, craft something,...)
3. after 1/2 minutes it blocks completely
