During my minecraft sessions I've noticed a little line on my screen where the pixels are glitched. It only happens when the player is moving and I've had issues with it as have one of my friends. I've heard some youtubers complain about it as well, and they were using windows, so it is not just a mac problem. I couldn't get a picture of it, but I did circle the area of the problem. I'm not sure what's up, but it's been bothering my eyes a lot so I thought I'd report it.
