Subject: 25.0.50; Underscore hidden by underline
Date: Tue, 05 May 2015 22:13:14 +0200

When `hl-line' is enabled with the `underline' attribute, and when the
font is "DejaVu Sans Mono" in 8 pt, then underscores get overridden by
the underline (of the current, highlighted, line).

Minimal config to reproduce the problem:

--8<---------------cut here---------------start------------->8---
(modify-all-frames-parameters '((font . "DejaVu Sans Mono-8")))

(global-hl-line-mode 1)

(set-face-attribute 'hl-line nil
                    :underline "#FFFF19" :background "#F6FECD")
--8<---------------cut here---------------end--------------->8---

Is this normal (while this does not occur with 9 or 10 pt faces)?

If yes, is there a way to get the hl-line's underline in the background?

Best regards,
Fabrice
