Holdable models corrupted

Phone: huawei P9
With 1.1.1.1 Beta after some play time if the app loses focus ( devices goes to sleep or switching tasks ) the models you can hold are completely corrupted.

Save & Quit freezes minecraft ( seperat bug I think ) but starting the game again and the corruption is gone, but will come back if the app again loses focus after "some" playtime.

Attached images are from two different days with the phone having been reset inbetween
