Linux: Memory handling seems far worse compared to 26.3

Create a new world in 26.3, go into Spectator mode, and just fly around for maybe 10 minutes generating chunks. Keep a good eye on how much system memory this consumes.

Now repeat this on the latest 26.4 snapshot. A lot more memory will be used up without being fully cleared out, and this will even persist if you exit to the main menu.

This may or may not be a Wayland issue: https://discord.com/channels/1138536747932864532/1424838212702044190/1556558467173720085
