unpracticable X display (Xquartz) for remote graphic connexion with ssh

Using Xquartz with ssh -X and emacs started from a remote server is un practicable almost always.

It works well from a PC and a Linux box.

It is a bit better if i downgrade the number of colors used but remains not usable on a per day basis.

A lot of researcher used Mac OS for connection to clusters for computation , i hope Apple will find a solution.

For now i forced to use my personal PC laptop under linux instead of Mac OS.
