Very low fps with biome specific grid colormap to grass_block

[s-k-y-l-i]

Hi!

This is my code: { "format": "grid", "source": "./white.png", "blocks": ["grass_block"], "grid": [ { "biomes": [ "terralith:birch_taiga", "terralith:moonlight_walley", "terralith:lavender_valley", "terralith:lavender_forest", "terralith:sakura_grove", "terralith:sakura_valley", "terralith:orchid_swamp", "terralith:shield", "terralith:yellowstone", "terralith:moonlight_valley", "terralith:moonlight_grove" ], "column": 0 } ] }

And it makes a huge fps drop to 3-4 FPS. If i change the blocks to "grass" for example, it doesn't lag, but the grass block is.

I have sodium.
