Also experiencing it (on version 1.21.2) when enabling beta-apis. Required a hard re-install of Minecraft after disabling enhanced input to eliminate this issue on vanilla worlds that had the Beta APIs checkbox enabled.
Can confirm on 1.21.31 hotfix. Disabling "Improved Input Response" and restarting the game fixed the high memory usage and leak.
When I first open Minecraft:
When I'm in a world with a high render distance with "Improved Input Response" on.
After exiting the world:
I have the same issue. I play on Minecraft Bedrock, and it is eating 12GB RAM to 16GB RAM. I only have 5 Add-Ons active.
CPU: Intel Ultra Core 9 285K
GPU: RTX 4060 Ti
RAM: 32GB 4800 MT/s
Can confirm.
