Check out the notes under "-X": "...For this reason, X11 forwarding is subjected to X11 SECURITY extension restrictions by default. Please refer to the ssh -Y option..." and then under -Y "Enables trusted X11 forwarding. Trusted X11 forwardings are not subjected to the X11 SECURITY extension controls." You don't have to say -XY, -Y is sufficient by itself. And of course -C is for compression. man ssh!
