The bug was described in bugzilla as an issue with Chinese fonts here:
This bug affects the rendering of all bitmapped fonts
, not just Chinese ones.
I'm attaching a screenshot from gnome-terminal. The font should be MiscFixed; this happens about 1/3 of the time a bitmap font is displayed with the following config: Fedora 9, nvidia driver 173.14.05 & Xorg 220.127.116.111 (1.5.0 rc 1) on a 2.6.25 kernel w/gnome 2.22.1 and a geforce 6600le...
This hyar be the problem, boys:
