Weird white spots on vegetation/trees?

I have only found one similar question and their fix didn’t work for me so I will post a new question. So basically there are random white spots on the textures of the bushes. I have tried setting alpha cutoff to zero. When I did that, it worked for 5~ mins, and then it reverted back to how it was before, with the white spots even though alpha cutoff was still at 1.

Fairly sure this was fixed with recent Unity update, or fixed by using a proper terrain shader. If you have instances of this now, please update.
