In this pretty Wine/Proton specific kludge, we try to handle confining grabs on InputOnly windows by trying to find the InputOutput window that the pointer would get visually confined to. The grabbing window and the visible window come from different clients, so we used to simply resort to the pointer focus. This is troublesome though, as the call may happen very soon at a time that the toplevel wasn't yet mapped by the Wayland compositor, so the pointer focus may well be out of date soon. In these situations, it does seem that even though the confining grab happens too early to have the wayland surface mapped, the xserver view of the WindowPtr does already reflect the size. Use this to find out the better window to assign the confining grab to, one whose geometry fully contains the InputOnly window's.

X Server
The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into.
Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.
