+Subject: x11/window: Ensure we send a ConfigureNotify to just mapped windows
+
+When managing a non-OR window we're required by the ICCCM to behave as
+if we received a ConfigureRequest which means that we must generate a
+synthetic ConfigureNotify even if the window isn't moved or resized
+from its current (initial) geometry.
+
+During MetaWindow's x11/wayland split a slight behavior change for x11
+windows crept in. Before the code split, MetaWindow->rect was
+initialized with the X window's geometry, but now we're not
+initializing MetaWindowX11Private->client_rect which causes the checks
+for whether it's necessary to move/resize the window in
+meta_window_x11_move_resize_internal() to tell us that we do need to
+move/resize which means we do an XConfigureWindow() call and don't
+send the sythetic ConfigureNotify. But since the X window isn't really
+moving, the XConfigureWindow() call doesn't cause the X server to
+generate a ConfigureNotify which breaks some clients such as Java's
+AWT.
+
+We can fix this by setting MetaWindowX11Privatew->client_rect for both
+OR and non-OR windows. We can set buffer_rect for non-OR windows as
+well to simplify the code since it will be assigned the correct value
+in meta_window_x11_move_resize_internal() .
