      Sometimes (but not often) the game starts to have extreme lag spikes - several seconds of the same frame - and it seems to happen because the memory usage goes to 98% to 99% (maybe even 100% but I have not seen it), possibly because it cannot release unused memory resources fast enough.

      Even the menu when the game is paused is extremely laggy (but not the main menu).

      I'm playing with 2 GB of reserved memory (8 GB total) as set via the JVM arguments profile option ("-Xmx2G") and this has never happened to me before (even when I used to play with only 1 GB of memory).
