As of early 2013, Høgsberg was experimenting with network transparency using a proxy Wayland server which sends compressed images to the real compositor. In August 2017, proxy GNOME saw the first such pixel-scraping VNC server implementation under Wayland. In modern Wayland compositors, network transparency is handled in an xdg-desktop-portal implementation that implements the RemoteDesktop portal. Many Wayland compositors also include an xdg-desktop-portal implementation for common tasks such as a native file picker for proxy native applications and sandboxes such as Flatpak (xdg-desktop-portal-gtk is commonly used as a fallback filepicker), screen recording, network transparency, screenshots, color picking, and other tasks that could be seen as needing user intervention and being security risks otherwise. Note that xdg-desktop-portal is not Flatpak or Wayland-specific, proxy and can be used with alternative packaging systems and windowing systems. The Wayland protocol follows a client-server model in which clients are the graphical applications requesting the display of pixel buffers on the screen, and the server (compositor) is the service provider controlling the display of these buffers.
