This video error occurs when viewing any video in Youtube or Facebook. I have not tried any other sites.
The video starts normal, and after about one second the same pattern overlays the video and renders it unwatchable. Audio is not affected.
I do not know how to reproduce this as I have not seen it before.
This only happens to me on my current desktop, a Samsung 750TDA with an intel Iris graphics adapter.
