It just happened to me again and I decided to clip it. Still no idea what causes it but it happens once in a while. and it does appear to be pixel perfect on the edge.

I think you should keep it because it would make things more interesting for Speedrunners. I don't think it would happen enough to normal players to really be an annoyance and cause any harm. But also if you remove it I'll just keep playing on the vanilla version for the sake of faster times in the future. You could remove it and have the removed and non removed versions both available but honestly I don't think its that big of a deal for the general public that will play this game. And for Speedrunners it seems to be the next big key to getting crazy times so I ask that you keep it please.
