What do you mean "Desktop UI"? Do you mean like a gnome (or other
"productivity environment"), etc? The machine I run myth on that
displays to a CRT is dedicated to being a myth frontend and tuned for
that function. There is no deskotp. There is only X and the myth UI
window on top of it.
As such, I have tuned the overscan with nvidia settings so that when I
am watching myth, I see the exact same visible area as I would see with
regular TV. This is unlike of course watching that same channel in a
window on a desktop as that mode includes the area around the picture
that would normally be hidden by overscan.

No. It doesn't because the design of the UI on the myth window has
never accounted for overscan. I tend to think it's been designed in a
window on a desktop computer where the edge of the "canvas" is visible,
unlike when it's shown on a device that has overscan.

My UI is the same size as my screen, aka "full-screen", which is
640x480. The problem is that with overscan, the 20-30 pixels around the
edges of that 640x480 are not visible with an overscan display.
