Stange enough: for me too (nightly cvs builds, so this is no more the
same CVS head), but in normal use the problem is still there...

Indeed this is a very annoying heisen-bug: I see the same symptoms under
varying conditions all the time, but its hard to get a reproduction
receipt.  A co-worker of mine has the same problems with a different
font -- both fonts have in common, that they are x11 bitmap fonts.

Maybe the used toolkit is a factor two?  This is with lucid (haven't
tested gtk2)...

For 3 (Terminus 12):
  x:-xos4-terminus-medium-r-normal--16-160-72-72-c-80-iso10646-1 
and for 4 (Terminus 11):
  x:-xos4-terminus-medium-r-normal--14-140-72-72-c-80-iso10646-1
