Weird Graphical Errors in Snapshot 15w32b

I've attached some pretty weird images from a world created in 15w32b. Before you ask, my graphic drivers are up to date as of 7-17-15 (the latest release). The missing textures (seeing through the chunk) never go away even if you leave and return. The black line in picture 3 shows up from either side if you fly through it. These occur on every world opened or created in the snapshot. Default texture pack.
