I’ve been playing around with the live borders. They were sort of limited before in that the internal scaling they do messed up scanline effects, despite the end result being integer-scaled (which is the main reason people use integer scaling…), so I combined them with some of the overlay effects to get perfect scanlines mixed in (click to full size to get the full effect):
You can lighten (or totally) remove the scanline effects using parameters, and I put in an overscan compensation setting, so it should let you get perfect scanlines (on 224 vertical res) whether you use the ‘crop overscan’ setting ON or OFF.

I haven’t pushed these up to the common shaders repo yet because I wanted to see if this is something people are actually interested in or if I should leave them as-is.
