Take any latex document with sufficiently many equations. After cloning an
indirect buffer ("C-x 4 c") and killing that indirect buffer (e.g., "C-x 4
0"), many of the overlays in the original buffer become invisible. Indeed,
one can check that the relevant subfolder of =_region_.prv= is rendered
empty, so the overlays that remain visible are just those that have been
cached.
This is undesirable: if one attempts to simultaneously use preview and
indirect buffers, one eventually has to regenerate all previews after
killing any indirect buffer.
The issue is that killing the indirect buffer calls
~preview-kill-buffer-cleanup~, which in turn calls ~preview-clearout~.
In my local version, I wrapped ~preview-kill-buffer-cleanup~ with ~(unless
(buffer-base-buffer) ...)~, as follows, so that it doesn't clearout
indirect buffers. This has resolved the issue for me, but I imagine it
could be useful for others who use both AUCTeX and indirect buffers.
#+begin_src elisp
(defun preview-kill-buffer-cleanup (&optional buf)
"This is a cleanup function just for use in hooks.
Cleans BUF or current buffer. The difference to
`preview-clearout-buffer' is that previews
associated with the last buffer modification time are
kept."
(with-current-buffer (or buf (current-buffer))
(unless (buffer-base-buffer) ; do not clearout indirect buffers
(save-restriction
(widen)
(preview-clearout (point-min) (point-max) (visited-file-modtime))))))
