When eglSwapBuffers inserts a new frame into a window's stream, there may be a delay before the state of the consumer end of the stream is updated to reflect this. If the subsequent wl_surface_attach, wl_surface_damage, wl_surface_commit calls are received by the compositor before then, it will (typically) re-use the previous frame acquired from the stream instead of the latest one. This can leave the window displaying out-of-date contents, which might never be updated thereafter. To fix this, after calling eglSwapBuffers, xwl_glamor_eglstream_post_damage should call eglStreamFlushNV. This call will block until it can be guaranteed that the state of the consumer end of the stream has been updated to reflect that a new frame is available.

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.
