Microsoft's Remote Desktop has had issues with gateways and the native fullscreen of MacOS for years. When connecting to a gateway that works in fullscreen, the application miscalculates the size of the macOS taskbar, with the entire view shifted up and off the screen at the top. Even the mouse pointer on the remote machine clicks several pixels below where it actually is (precisely the size of the macOS taskbar) The workaround is to put the connection manager in fullscreen *before* connecting, which ends up preventing open other simultaneous remote connections. A real shame. In the first attachment you can see the green MacOS wallpaper at the bottom of the screen. In the second attachment, the mouse on the remote desktop is exactly over the link written "MARCA".
