Date: Fri, 5 Jun 2015 22:24:00 +0200

Dear Auctex team!

The preview feature is not working for people that have

\usepackage{tikz}

and some other common stuff in their document. This is really a pity.

How can we actually solve this problem?

At least a workaround?

Filing Bugs does not seem to lead anywhere, considering that it was filed

Yes, I know.  Unfortunately, my TeX/PostScript knowledge is far too
limited to do anything about it.

Find someone with the right skills who knows how to fix the issue.  At
least this issue has the benefit of being easy to reproduce, e.g., this
MWD will do.

--8<---------------cut here---------------start------------->8---
\documentclass[a4paper]{article}
\usepackage{lipsum}
\usepackage{tikz}

\begin{document}
\(a\)

\lipsum{}

B \(b\).  C \(c\).  D \(d\).
\end{document}
--8<---------------cut here---------------end--------------->8---

> At least a workaround?

No, sorry I don't know any workaround except for commenting out the
\usepackage{tikz} when generating previews. :-(

Bye,
Tassilo

Isn't this https://sourceforge.net/p/pgf/bugs/316/ again ?

For some reason, it seems that upstream is not fixing it even though a
patch is available. FWIW I've been running with that patch for a few
months have yet to see a problem with it.

Oh, yes, seems so.  And 315 seems also related.

Why do you think that?  AFAICS, no official has done a statement on
that, and the issue is just one year old.

Which one?  And do you also save \shipout before \begin{document} and
restore it afterwards as indicated by the comment by Kirill Müller?

In any case: if there's anything that we could put into preview.dtx to
fix the issue from our side, that would be awesome.  Patch welcome!

Err... yeah maybe I'm being pessimistic again.

The "correct patch". More precisely, it's :

I don't.

I admit I haven't looked into it, but I'm afraid I won't be able to
help.

Hehe, but yes, one year without official comment sounds like at least
nobody is especially interested in the issue.

Hey, cool.  I patched my
/usr/local/texlive/2014/texmf-dist/tex/generic/pgf/utilities/pgfutil-latex.def
with this corrected version, and now previews work at least in the
minimal test file I've used to reproduce the issue.

Me neither and still seems to work.

Ok, no problem.

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

This is what I get with a recent AUCTeX and Emacs:

[preview.png (image/png, inline)]

[Message part 3 (text/plain, inline)]

The result looks Ok to me.  I'm closing this report for now.  We can
reopen if you get other results.

Best, Arash
