For sure does it through most of this specific episode S02E17...very noticeable in lighter greyish backgrounds...I do not see it happen in other episodes so far though, but have seen it happen in others before i thought to take a pic of it.

Edit: Seeing this line again when i bring up the seek bar at certain times in S03E01.
Seems to be best seen when there is some grainy or compression noise in the picture. But am seeing it almost at any time through out the entire episode, it very very faint at times, but it is there. But then not at all in other episodes. Very strange.
