bug#10104: Extra empty space at bottom of frame under Xfce, athena toolkit

[Glenn Morris]

[-- Attachment #1: Type: text/plain, Size: 679 bytes --]

Package: emacs
Severity: minor
Version: 24.0.91

If I build Emacs using --with-x-toolkit=athena --without-toolkit-scroll-bars,
then on GNU/Linux (Debian testing) using the Xfce (4.8) window manager,
with emacs -q --no-site-file (or -Q, so that X resources are ignored),
there is extra blank space at the bottom of graphical frames. It looks
to be about half a line high, and has no scroll-bar or fringe
(screenshot attached). Resizing the frame does not make it go away.

This occurs with 23.2 onwards, but not with 22.3 or 23.1. It does not
occur with a Gtk toolkit build of any version. It does not occur in a
Gnome 3 or Window Maker session, ie seems to be specific to Xfce.

I can't repeat this.  What is your default font.
Also, those colors are not the Emacs defaults, so how do you get them when starting with -Q?

Sorry; I was using -fg white -bg black for illustration because I
thought it made the issue easier to see. The menu-bar colour came from
X resources, which are not ignored with -Q for Lucid properties.

This prompted me to check my X resources, and it turns out the issue is
caused by:

Emacs.pane.menubar.margin: 3

Using anything other than 1 here gives me the extra space at the bottom
of the frame. The font does not seem to matter. It happens with both the
system default
xft:-unknown-DejaVu Sans Mono-normal-normal-normal-*-13-*-*-*-m-0-iso10646-1 

and my normal
x:-misc-fixed-medium-r-normal--15-140-75-75-c-90-iso8859-1

I still can't repeat it at startup, but I see it after I resize the Emacs frame.
I have checked in a fix for that, hopefully it cures your problem as well, I'm sure they are the same bug.
Please try it.

Thanks,
