After updating to the 1.5 version, the game uses a huge amount of memory and has terrible lag

The game is consuming astronomical amount of memory, causing terrible lag. Few minutes before playing the new version I updated Java from 16 to 17, so I don't know if this problem is really caused by the game or by the new Java version.

I created a new issue because I don't know the cause, so I'm not able to simply vote or comment on another issue.
