Device
This was on Lenovo Tab3 7 Essential Android 5.0 Mali MP GPU.
Description
When you go to the world on Minecraft, you will see the normal textures. When you want to record something or get something from another app, you have to switch between Minecraft and the other app.
When you're done with that app, switch back to Minecraft. You will see that only blocks is affected by this texture glitch.
The GUI, items, particles, texts, etc. are fine. When you exit the world, you will get a chance that Minecraft will go to the white screen, otherwise, you will see "Done", then the whole Minecraft will turn into the blue sky in the world background and you have to restart the app to fix it.
It will also do this after you turn off the screen and turn it back on.

Steps for reproduction
