Hi John,

I don=E2=80=99t have a comment on the substance of the proposal, but rather=
 two
suggestions for workarounds.

The first is to use the C-c C-v C-e binding to execute source blocks
rather than C-c C-c.

The second is to let-bind =E2=80=98org-latex-fragment-image-overlays=E2=80=
=99 to nil
in an advice around the =E2=80=98org-ctrl-c-ctrl-c=E2=80=99 function, allow=
ing you to
still use the more convenient C-c C-c binding.
