Can you please post some small screenshots exhibiting the difference?  I
mean, `overline-margin' has this docstring:

,----[ C-h v overline-margin RET ]
| overline-margin is a variable defined in ‘C source code’.
| 
| Its value is 2
| 
| Space between overline and text, in pixels.
| The default value is 2: the height of the overline (1 pixel) plus 1 pixel
| margin to the character height.
`----

and `underline-minimum-offset' has this:

,----[ C-h v underline-minimum-offset RET ]
| underline-minimum-offset is a variable defined in ‘C source code’.
| 
| Its value is 1
| 
| Minimum distance between baseline and underline.
| This can improve legibility of underlined text at small font sizes,
| particularly when using variable ‘x-use-underline-position-properties’
| with fonts that specify an UNDERLINE_POSITION relatively close to the
| baseline.  The default value is 1.
`----

Is the distance between the two lines so huge?

Best, Arash
