Status: VERIFIED DUPLICATE of bug 30579

Once a Mozilla window (browser or mailnews) has a vertical *and* a horizontal
scrollbar, there appears a gray square near the lower right window corner, right
where the scrollbars meet.
Its gray color might look ok with the Windows default color scheme, but not with
other color schemes.



Reproducible: Always

Steps to Reproduce:
1. Open browser (or mailnews)
2. Make the Mozilla window get a horizontal and a vertical scrollbar (by loading
a document (or mail) that is too wide and too long to be displayed all at once)
Actual Results:  
Near the lower right corner, where the scrollbars meet, there is a (dark) gray
square , no matter what Mozilla theme or OS color scheme is currently active.

Expected Results:  
That square's color should depend on Mozilla theme and/or system colors.

This gray color is hardcoded in nsViewManager.cpp, line 1116
(http://lxr.mozilla.org/seamonkey/source/view/src/nsViewManager.cpp#1116) and
was introduced in its revision 3.160 with bug 39621 as a default background color: 
" // There are some bits here that aren't going to be completely painted unless
we do it now.
  // XXX Which color should we use for these bits?"

However, in the 1.0.x branch this square still appears white (as it did for a
long time). Probably this gray is overpainted there...
This got changed somewhere after the 1.0 branching, before the first 1.1 builds.


Because of the location of the responsible file I chose "Views" as component,
but another one might be better suited if it was responsible for overpainting
that square and somehow stopped doing so earlier this year...

This probably is all/all, but I could not test it.

Here you easily see how that square is always gray with different color
schemes.
