Thanks.

I think the problem I've been seeing is a different one. While trying
to solve some other problem I discovered that my problem was linked to
issues where Xresource font settings seem impose themselves too
strongly, so the font-backend used was most likely X rather than xft (in
my case) and the problem disappeared if I removed those font settings
and let the font be specified some other way. I.e. I'm glad you found
your bug, but mine is still around, and is probably
elsewhere altogether.

Yes, I saw that. I found it curious, but was actually happy about it:
I prefer my line to be 2 pixels thick (Emacs-22 makes it even thicker,
BTW).
