This issue is now irrelivant. Please close this.

I have noticed that the game has been running out of memory A LOT lately compared to previously when doing other things in 1.19.4 and in 1.20 snapshots, no matter how much memory you allot to the game. I have tried 2 GB to 5 GB and it still runs out of memory. I thought it was my GPU but my GPU will be like 26% or something but the game will be super laggy.

I can't confirm for 100% sure that this is caused by a memory leak but I have noticed what you described.

@Brevort, My game tends to use a lot less memory than it should.

Possible explanation:

The game is allocating memory instead of using it like it should.

We do not have enough information to find the cause of this issue.

While the lag occurs, please press F3 + L once, then wait a short moment until profiling has finished.
Afterwards, please attach the generated .zip file containing the profiling results here. The file path is shown in chat; the file can be found in [minecraft/debug/profiling/<DATE>.zip|https://minecrafthopper.net/help/finding-minecraft-data-folder/].

If you are playing on a server please additionally run the command /perf start to create a profiling report for the server. In case you do not have the permission to run this command, make sure that you're a server operator.
Once profiling has finished, please attach the generated .zip file from debug/profiling/<DATE>.zip of the server folder.

_{This issue is being temporarily closed as Awaiting Response. Once the requested information has been delivered, the report will be reopened automatically.}

I will try my best, It sometimes works just fine or it lags like crap, if it does I will get the profiler file

Logs and a Screenshot have been added

UPDATE: Its probably not a memory leak but the "bad chunks" issue from 2009 where it lags tremendously when loading new chunks

Close this, it was a problem with my Windows installation (witch crapped out about a week later) switched to Ubuntu and everything was fine 🙂
