Issues compilation (generation and textures)

I've uploaded some screenshots in order to report some texture and generation bugs that I've been seeing. First screenshot shows that water can be seen through particles. The second and third one shows that upper textures in "double-placed" doors are looking on the wrong direction, and that doors have hinges on the wrong place again. In fourth and fifth images, you can see End crystal's pillars generated under the "dragon island" and some invisible end stones. In the last two ones, you can see that zombie villagers legs are invisible (the white robe doesn't hide them). Thank you for reading, and sorry if you don't understand something, I'm Spanish (I think).
