Nothing to discuss really, it is more of an info for those who did not bother to read the last patch notes, and I do believe there are plenty of people who did not, grass distance render is added to Video options now.
Why a forum thread?
Because per default, once it is added, it is set to Low
And I think most of us didn't look at the video settings for a long time, if ever from the time you set them up.
So go and tweak that so you grass distance is not set to low.
