Whenever i log in to a server or a singleplayer game, all the blocks are invisible, there is no texture on them but i can see the black outlines of the blocks and i can destroy them. I have no mods installed, tried to redownload all the minecraft files, but it didn't work. Tried also to install a resource pack, but that did not work either.
