memory leak (suspected rendered chunks never freed)

      Problem: Free memory does not increase in substantial amounts (<25 and not often). Continued rendering of chunks will allocate more and more memory that is not accounted for by game's counted in-use memory. Frame rate drops and either the game re-renders with minimum render distance or crashes.

       

      Steps to reproduce: load a new creative world on version. Set render distance as high as possible (not required, just faster repro). Wait for render to complete. Notice that memory stays constant. teleport somewhere far away. Repeat steps until crash or re-render. Does not depend on teleport, it is just a faster repro.

       

      Seen this in 2/2 new creative worlds.

       

      not using RTX/not on RTX world.
