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() . https://bugzilla.gnome.org/show_bug.cgi?id=759492
