Graphical Chunk Glitch (Invisible Blocks; Passable Floating gravel; ect

Changing render distance causes this glitch(6 to 8; 8 to 16; ect.)

-Invisible blocks(I can collect them, Sand; dirt; stone; sandstone; coal ore; iron ore; ect. Can still walk on them too.)
-Passable Floating Gravel
-Floating Caves (I can walk straight through them. I never checked if I could collect the ores or not)
-Terrain and Biome Changing(only visual as they didn't actually change)
-UFOs(Seriously I have no idea what they are, they float around and spin, they have weird textures and different colors too. I didn't hear about these being added. I can't punch them and they don't attack me either, so it's not a killable entity)
