This morning I loaded minecraft, created a snapshot profile, and created a world. All the places where there's normally water where covered in a polished granite texture. But then I tried to land on this Granite I went right through it. And It turned out only still water is affected.
When you put your cursor on the block it doesn't recognize it, because it's not a block. I placed an actual polished granite next to the glitched water, and the texture of the glitch is actually shorter. Then I tried to see If lava was glitched too. It was but instead of the granite texture it was covered with the lapis texture.
Also, when I hoped in it, my screen where covered with the texture of the "Locked Chest", with black and purple squares.
Leaves blocks are also glitched. I was wondering In the forest, and trees appeared to be changing around me. I realized that the texture of the leaves went from a hollow kind of texture to a plain one, when I was getting close enough to them. Also, if you hold a leave block in your hand, the texture is hollow, but when you place it, it's filled.
That's two main bugs I found.
