      Placing a mob spawner with a mob that has an invalid death loot table causes major graphical performance issues when looking at the spawner.

      To recreate this, here is an example command:

      give @s spawner{BlockEntityTag:{SpawnData:{entity:{id:"minecraft:zombie",DeathLootTable:"this/is/invalid:loottable"}},SpawnPotentials:[{weight:1,data:{entity:{id:"minecraft:zombie",DeathLootTable:"this/is/invalid:loottable"}}}]}} 1 

      My minecraft log reports the following:
