When the game prints console messages about "changing chunks", greenhouses onscreen briefly flash to showing dry soil (with a water drop icon if there is a plant growing).  It happens crossing either direction. I tried Linux version 0.50.2 and the Jul 25 build of 0.51.

I doubt the console messages are interesting, but here's what they look like:

[MoonBase] Player: changed chunks!: 49, 50
[MewnBase] ChunkLoader: loading ground tiles for 48, 49
[MewnBase] ChunkLoader: loading ground tiles for 48, 50
[MewnBase] ChunkLoader: loading ground tiles for 48, 51
[MoonBase] Player: changed chunks!: 50, 50
[MewnBase] ChunkLoader: loading ground tiles for 51, 51
[MewnBase] ChunkLoader: loading ground tiles for 51, 50
[MewnBase] ChunkLoader: loading ground tiles for 51, 49
