Sorry, I should have specified my configuation, shouldn't I?
I built without Xft - and the problem also appears on tty frames.

./configure --with-mule --with-athena=xaw --with-xim=xlib --with-mail-locking=lockf --with-optimization --prefix=/home/jcb/local --without-debugging --without-error-checking
