Possible Memory Leak issue with update 1.16

Since the update yesterday, my computer is suddenly being heavily taxed by running Java edition. It now overheats and watching my task manager Processes, the memory is upwards of 6000 MB which is significantly higher than before, when I had no issues whatsoever. I have been told it may be a "memory leak" issue. Was also told it may be related to the MC-164123 bug as well, however the symptoms seem different as I am not experiencing in game performance issues.
