I have two Mac OS X clients, both running XQuartz 2.1.6 (xorg-server 1.4.2-apple33). When I SSH into a remote linux system enabling X11 forwarding and launch gnome-terminal, on one Mac the terminal looks correct while on the other, the fonts are all screwy!
[jnet@Stan ~]$ ssh -X [email protected] gnome-terminal produces: 
powerbook:~ hp$ ssh -X [email protected] gnome-terminal produces: 
The problem goes away on the powerbook if I zoom in twice: 
Edit: This affects a number of apps, not just gnome-terminal. It also affects Thunderbird, for example.
[x11][fonts], can anyone help a new user out?
