Hey guys, so I've noticed that whenever I'm watching a video on say VLC, and I maximize the view, I notice a sudden disruption in the picture. This happens very intermittently and is often short lived, but I was hoping I could get some opinions on why this might be happening and how I can fix it? Any help is much appreciated. I've attached a screenshot of what I see on the screen to this post. I have a 2011 13" MBP btw.
