You are probably right.  Digging into this a bit further I found that
calling gui_consider_frame_title for child frames fixes it.  So it looks
like a combination of explicitly selecting a frame via Fselect_window of
its selected window and subsequently calling init_iterator would orderly
rebuild the face cache of that frame.  A wild guess, I know ...
