Have no idea. Is antler22's foliage, so it should look fine. Happened to me all the time on a laptop 3060 gpu. On mac all the textures render fine... My thought is that you mentioned that your pc struggles with 4x map, so might be rendering problems...
Nah my new pc does well with 4x, but on the base judith plains the alfalfa looks different to me than wht I spawned on your edit. I will have to look again, but either way its no biggie and loving the new crops.
