Anyone have any idea what could be causing this flashing up on my screen when i'm watching video.
I don't know how to describe it but in the video you can see like black pixels flashing up at 0.06, 0.10, 0.21

It seems to be mostly when watching HD video's on the internet it doesn't happen when i'm watching films etc using iTunes.
I have tried wiping my Mac and starting again, updating to Mavericks didn't solve it, It's been happening since I had Snow Leopard.
