In any case, if they are just guidelines, that would just be transient
in the FontForge display, so not likely they are connected to triggering
the Acrobat rendering bug. Which, BTW, has anyone reported it to Adobe?
As for a workaround in the font, looking at dumps from ttx is all I can
think of to see what's really different and what might be changed. It
could be anything. I won't be able to do this any time soon, but I'll

whether it's connected to hinting.
In principle there should be no hints in Lucida fonts, unless FontForge
decided to add them on its own hook. B&H (intentionally) never defined
