If you look closely at the pictures posted in the thread you should see green lines that's the best I can describe them really. If you cant see the 3rd image id be amazed as it painfully obvious.
Those were snapshots of videos playing. Basically green something maybe distortion of some kind that shapes around the curves and movement of video playback. ALL videos regardless of source do this when the issue is happening. The only remedy was lowering the refresh rate under settings from 60hz to like 59 or 50. Only thing that came to mind was "graphics card?" otherwise I have no earthly idea.
