Does shutting the machine down, waiting an hour and then powering it up help?
If so then the CPU overheating. I had this problem first 2 years ago with 
Windows95 and AMD K5/90. Some CPU's, notably AMD's, have serious problems 
with floating point ops when they are too hot. In win95 it showed up as 
dropped characters and font substitutions (didn't use linux yet). In the long 
run (after 45 minutes of use) all truetype fonts were dead and bitmapped ones 
were substituted. I presume that xfs type1 renderer will gracefully foldback 
to substituting bitmapped fonts when there are math errors, although this is 
just a pure guesswork (no time to look into xfs sources). Well, my cpu was 
really hot as the fan was dead. ;-)
