It's needed when the surface window is a depth 24 descendant of a depth 32 toplevel window. xwl_source_validate ensures the toplevel window pixmap has valid contents when a client reads from it, or when the window hierarchy / geometry changes. It's never called in the normal fullscreen application case, so there's no GPU copy overhead with that. v2: * Don't try to redirect a depth 32 descendant of different-depth ancestors, the alpha channel wouldn't be handled correctly.

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.
