Take a look at this video for a better idea: https://i.imgur.com/hDnTckc.mp4
It started a while ago. In the beginning it would be only small portions of the screen, and then as the screen warmed up it would go away, but recently it covers the whole screen and no longer goes away. If the input is black it sometimes doesn't happen, but as you see in the video, if theres a bright pixel, the green pixels after it will light up. And not all of them, its every nth one. If the resolution is lower, the green pixels are farther apart. It happens on all inputs (cdmi, DisplayPort and dvi). Interestingly, it doesn't happen to the onscreen menus, those are pristine and don't cause streaking either. So I suspect the panel itself isn't the issue, but something to do with the mainboard itself. I Took a look at it but none of the large caps seemed off (if that even is the issue). I'm not sure if what else I can look for.
