Hmm... while I guess it's still possible, it normally shouldn't happen: if the fontification takes place during the scrolling itself, then the next redisplay should not be skipped (and hence you should see fontified text rather than unfontified text, tho, some of the displayed text may still be unfontified, because it was marked as "fontified=defer" in the previous redisplay). So, if the text scrolls by fully unfontified, it should be the case that fontification did not happen during scrolling. Stefan
