While using the Caves & Cliffs preview datapack, after several minutes of gameplay I experience frequent lag spikes. This occurs when moving any distance less than one chunk.
Today I started a Large Biomes world and began building in a Savannah. After briefly leaving the Savannah biome and returning, the biome had changed to an ocean biome. All the original terrain remained, but now the grass and leaf colors had changed.
Environment
OS: Ubuntu 20.04
