Still happening in 1.20.2

Update: Still happening in 1.20.

New Thing: For all Minecraft versions, fps have been decreased and cpu & gpu usage increased, lwjgl calls seem to consume a lot more than before. Can confirm no changes to lwjgl library files or gameinstallations. Only possibilty seem to be windows or minecraft launcher.

Another Test:
I have 8GB of ram, 2,5GB used by operating system and 3GB allocated to minecraft, f3 screen shows 1,4gb-1,9gb used memory, allocating more memory does make it worse

No, the leak is outside of the java heap and not server side. Its not happening on the server side at all. Please dont mark as resolved.
