Which doesn't answer my question.  Did you do an "rm *.png" in the
recordings directory?  If so, you'd get the exact behavior you
describe.  The reason is because /regardless/ of whether you enable or
disable "Display thumbnail preview images of recordings," they are
generated (and Myth will look for them).  If you delete them,
mythfrontend will try to re-create them so they're there when needed.

If you're not deleting the PNG's, you've probably specified a location
for channel icons that the frontend can't find.  If going into the EPG
shows an equally annoying delay, this is the problem, so you need to
actually make those channel icons available to the frontend (i.e. by
copying them to the frontend or mounting the directory that contains the
icons in the path specified in the DB).
