Crash when using Deferred Technical preview

The bug consists of 

 

1 - open the game with a medium cell phone

2 - I put a PBR texture in a world (it has to be in the latest Minecraft beta)

3 - open the world

4 - wait until the message appears on your cell phone (it only appears when your phone crashes)

 

Obs:This message will continue to appear until you press close the game
