I have the following preferences:

browser.display.use_system_colors=true
browser.startup.page=0

but I observe when I start latest Minefield 4.0b2pre on Windows XP
(and number of builds in the last week or two) I get a pure white
background, although my system preference for Window color is silver
(#C0C0C0):

This appears to happen with every new window I open, also. Opening
a new blank tab in a window results in a correct colored background:

Switching to the first tab of the window still shows the white
background. I also notice a flicker of white background for a
moment and then reverting to my Window color when opening a new tab,
like:

Quite annoying for me. Don't know about people using a
high-contrast black color theme.

I've downloaded latest Shredder nightly and observed the bug it
describes, but no, it doesn't appear related.

The Shredder bug is about having the message pane not filled with
the Window/-moz-Field color, but with the Dialog/-moz-Dialog color.
This appears only initially before any message has been previewed
yet. After I preview a single message and select a different folder
with no message selected, the message pane gets painted with the
Window/-moz-Field color.

The problem with Minefield I get is the browser area of the initial
tab is painted with a fixed white color while I don't have such
setting/preference anywhere.

Interesting enough, after a restart caused by the automatic updates
the initial tab of the first window shows the correct (system set)
background color. The white-flicker while opening new tabs
continues to happen and any new windows get their initial tab
incorrectly painted with white background.

O.k. Digging it some more. Looking at Firefox 3.6 I see the same
"flicker" when opening a new tab but it is between Dialog and then
my Window color (which is much less obtrusive as I haven't noticed
it until now). Using the DOM Inspector I can see the xul:tabpanels
styled with 'background-color: -moz-Dialog' in Firefox 3.6 and with
'background-color: white' in latest Minefield.

I could really be related to Bug 575615 Neil has mentioned in
another reply to this thread. I guess the Firefox devs has tried to
hide the problem of not painting the browser area properly where it
gets filled with the underlying Dialog color of the xul:tabpannels
by making it white simulating a blank page, which however doesn't
look nice on all systems.

But looking at it more, it may really be the same. Please, see my
other reply (to myself) in this thread:

The regression range I've been able to identify is:

(good)

(bad)
