Memory leak when loading chunks with the "Improved Input Response" option enabled

Steps to Reproduce:

1. Enable the "Improved Input Response" option in Settings > Video
2. Restart the game
3. Create a new world
4. Fly around the world for a while
5. Observe the RAM usage in Task Manager

Observed Results:
The RAM usage keeps increasing as the player loads chunks. Eventually, the game uses up most of your available RAM. This occurs in both new and old chunks.

Expected Results:
No memory leaks should occur.
