As I already mentioned, if your face for the display string doesn't
specify a background color, the hl-line background color will be used.

If that's not an option, perhaps you could do that dynamically, by
changing the face of the display string whenever the hl-line overlay
is on the line where you have your display string?

Or maybe someone else will have more clever ideas.
