world generation in newest snapshot is strange

Some chunks // blocks (involving water or ice) have multiple different biomes depending on the angle of the player having the f3 screen open.
E.g one block //chunk is in a ocean biome and a lukewarm ocean biome or in a different spot one block is biome cold beach and lukewarm ocean or a block has the biomes lukewarm ocean and warm ocean.
I'm not sure if it can be reproduced .I would recommend flying to some ocean biomes .
