Large amounts of item entities are created when water or lava destroys decorations within lush cave biomes, resulting in performance drops

The Bug:

Large amounts of item entities are created when water or lava destroys decorations within lush cave biomes, resulting in performance drops.

This is a problem because over 300 item entities can be created as a result of this issue occurring resulting in noticeable performance drops when exploring lush cave biomes.

Steps to Reproduce:

  • Generate and load into a completely new world.
  • Summon a repeating command block that will alter the NBT data of any nearby item entities by making them glow.
  • /setblock ~ ~ ~ minecraft:repeating_command_block{auto:1b,Command:"execute as @e[type=minecraft:item,nbt=!{Glowing:1b}] run data merge entity @s {Glowing:1b}"}
  • Locate a lush caves biome and teleport to its location.
  • /locatebiome minecraft:lush_caves
  • Allow the chunks around you to load.
  • Take note as to whether or not large amounts of item entities are created when water or lava destroys decorations within lush cave biomes.

Observed Behavior:

Large amounts of item entities are created when water or lava destroys decorations within lush cave biomes, resulting in performance drops.

Expected Behavior:

Large amounts of item entities would not be created when water or lava destroys decorations within lush cave biomes, resulting in fewer performance drops.
