Interesting that it seems to be the OLED sets it’s happening on. Although it will be hard to tell from an image, here’s an example of what mine is doing from the menu on Splinter Cell. You can see that while it’s supposed to be a checkerboard like type of pattern, it alternates between that pattern and horizontal lines.
You can even see it on the font in “Create” over the letters where the lines are just horizontal. It’s even more noticeable here if you click “load full resolution”.
