Update Glitch Or Render Glitch Or Bug

I have found glitches or bugs in 1.8 I went to 24 render distance no lag the I had 1 pond of water by the way but anyway on with the story I went to 24 rd and went back to play and I saw millions of water puddles everytime I look down it glitches out and the guardians freak out with the models and textures no mods vanilla and I went through the ground and saw weird things I had no Guardians in the area by the way so it might be a updating render glitch or bug and this bug/glitch continues if you even go down to 2 rd even though the entitys stop wacking out the entitys disappear I can tell this from shadows heres some photos I took in the minecraft client! well I cant show you them but later Ill put them on my profile!
