Alan, If it is any consolation I can confirm your report on my Ubuntu system. Example 24 has not been updated since mid 2006 other than for a const char * tidy-up. The cookbook in in the example does say to use -drvopt smooth=0 so I suspect this is an old bug. I am still at a loss though as to the cause. Looking in gd.c and plfreetype.c the smooth_text variable appears in very few places - principally in the call to FT_Load_Char. There is nothing obviously wrong to me.
