<para>
The default value of this environment variable is 1. If changed to 0, this
disables the default use of client-side decorations on GTK+ windows, thus
making the window manager responsible for drawing the decorations of
windows that do not have a custom titlebar widget.
</para>
<para>
CSD is always used for windows with a custom titlebar widget set, as the WM
should not draw another titlebar or other decorations around the custom one.
