I recently came across a rather concise answer to an interesting question that was simply two short sentences:
For me, the render distance was doing it. I dropped the render distance to normal and now the blocks disappear like normal.
While the answer appears to have merit to me, I believe it's more of a suggestion, as in, this worked for me, you can try it, it might work for you. As a result, I mentally believe that the answer is more of a comment than an actual answer. However, I also noticed that a moderator edited the answer recently to clean it up, instead of moving it to a comment.
Since we are supposed to flag questions we believe to be comments rather than answers, I have to ask myself; what is actually considered a comment instead of an answer?
I realize that context will dictate this, and there's the classic examples where users don't have enough reputation to comment (which, could've been the case here originally, since the user that posted the answer only has 1 reputation point), or where the answer is obviously better suited as a comment, for example:
Did you try turning it off in the settings menu?
However, I'm at war with myself in this particular example, so, are answers similar to the one above, actually answers?
Note: I'm not questioning the moderator's decision here, merely trying to understand it.
