Read the FC3 Release Notes:
In section for openssh:
"The behavior of ssh clients that are invoked with the -X flag 
has changed. In OpenSSH 3.8 and later, X11 forwarding is 
performed in a way that applications run as untrusted clients by 
default. Previously, X11 forwarding was performed so that 
applications always ran as trusted clients. Some applications 
may not function properly when run as untrusted clients.To 
forward X11 so that applications are run as trusted clients, 
invoke ssh with the -Y flag instead of the -X flag, or set 
ForwardX11Trusted in the ~/.ssh/config file."
