Details:

The first application started in an X-Windows session using Window Maker as
window manager does not get a proper app icon and application menu. Instead,
the standard Window Maker application menu is shown when right clicking the
app icon as if the application was started with UseWindowMakerIcons = NO. If
the user default GSIgnoreRootOffsets is set to YES this happens for *every*
application.
Obviously, the problem is the code in XGServer's -_setupRootWindow method
that attempts to determine the dimensions of the window frame added by the
window manager. This code creates a few windows before the application creates
its app icon. Apparently, Window Maker creates a standard app icon with its
own menu when it becomes aware of the first of these windows and then ignores
the later request for a custom app icon from the application.
I'm not sure what a good fix for this problem is. Of course, we could always
special case Window Maker and just fix the window frame offsets for Window
Maker (hoping that they will never change :-). Maybe the backend could always
create an app icon window in advance before testing the window frame offsets
and then later use this window instead of creating a new one when the
application wants to create the real app icon window.
