Devastating texture glitch

I am running 1.10.0 on my Xbox and 1.10.1 on windows.
.When joining a Minecraft realm, most of the textures are gone. This has happened to me many times I will join a Minecraft realm and most textures are turned black and purple. I would have to delete Minecraft and reinstall it but on some devices like windows 10 and Xbox that will not solve the problem. This has also happened to some of my friends so it is not just me. I hope something can be done about this.
