1.3.4 Window Resize Margins

Window resize margins are supported by RDP 10.2. The dimensions of these margins are defined by the server and are to be used by the client to create a transparent hit-testable region around the RemoteApp window graphics. Any mouse, pen, or touch input within these margins is to be sent to the server.

Window resize margins must be used to extend the window geometry and are not included in the boundaries of the window sent in the Window Information Order (section 2.2.1.3.1.2.1).
