[Message part 1 (text/plain, inline)]

The background colour of Emacs when started in windowed mode if flawed
somewhow. Lines of text have another background than the overall editing
area, and trying to change the color via M-x set-background-color does
only affect the background color of the text lines. The same goes for
themes, even if a choose a theme with dark background this only affects
the background of the text, the rest of the editing area always stays in
a light grey. This is even the case when starting Emacs with the -Q
option. See the attached screenshot for a demonstration.

I'm using the Emacs sources checked out from the Bazaar repository just
today; my OS is Arch Linux 64-bits. Desktop environment is mostly XFCE,
with the exception for the window manager which I replaced with i3. 

Greetings,
Marvin

I'm afraid I can't reproduce this.  Doing emacs -Q followed by M-x
set-background-color RET light blue RET, the background of the entire
frame becomes light blue, including the non text areas.
