Game leaks memory and allocated memory (in my case 8 gigabyte) goes to 100% in a couple of minutes. Game starts to lag, chunks stop loading/unload. Tested this in creative, spectator and survival mode. When you close the game it takes about 3-5 minutes to save the game. Although the game doesn't crash it lags the entire computer as well, by minimalizing it to the taskbar. FPS isn't dropping though and i'm using the ingame java 17.0.1

Seems to happen in SSP only not exprienced this in SMP yet. My world is an existing world of 6 years old. This bug again returned, think it's the 4th time now.

Reproduce:

Load a single player map, and existing world (pre 1.17).
Go exploring,, gamemode doesn't matter.
Reload chunks, teleport, go to other dimensions.

Kind of sad that such a bug still occures in a full release, it's the 3rd or even 4th time this issue occures, quickly remarked as resolved, and the lable makes the report "to be ignored".
