After opening the launcher and selecting to play with the latest snapshot the start screen goes black/purple no textures, when i log into a world it is the same. Haven't used any texture packs or anything special.
Environment
Windows 10 Pro 64 bit (version 1703), Java Version 8 Update 151 (64 bit), 8 Gigabyte of RAM
