Since 0.60 throughout 0.62, there is constant dithering/white dots along with blue lines on trees and grass, it only exists for AMD cards.

I did send a bug report.
Steps to reproduce:
- Enable Alpha to Coverage; then click apply.
- After that, enable the setting below it, with the "All trees + Grass" value selected, the bug appears with any value, I said all trees and grass due to it enables both.
This setting makes vegetation look a lot nicer, but produces graphical problems for AMD users.
