      I was in Snowy Taiga buffet trying to survive. Suddenly, a thunderstorm started and everything became slower and slower till mobs almost didn't move at all. No FPS drops, just slow mobs.

      Other snowy biomes are okay, just Snowy Taiga and its variants are laggy

      This is caused by foxes pathfinding to 0, 0, which is described at MC-179916

      Best way to reproduce is to create a single biome (buffet) world with one of these biomes.
