EDIT: Managed to get the gliched textures, this happened after i left a friends world.

textures are bugged. Dirt looks like a weird command block. This is not my device as it is happening on a realm as well and other people can see it (see images below)

Below image is Global Resorces

Below Image is world-specific texture packs

This is the world

It seems like the textures seem to load most of the time but every so often the dirt and dead bush show this weird stretched purple command-block like texture.
