Grass and ferns grow where they shouldn't

In 20w22a, grass and ferns have been growing where it shouldn't I saw it on cobblestone in a village house. I also saw it on sand. I don't know if this is my graphics card (Radeon Pro 555X 2 GB) or this is everyone. I think it could be my graphics because it said there could be graphics bugs on certain graphics cards in the patch notes.
