Dear developers
When I open the original UserGuide with 2.4.0dev, I see this in the calling
command window:
Warning: dvipng failed to generate images from lyxpreviewOuMJqr.dvi...

When I open the French version, I get only the last line.
Any clue ?
Ghostscript chokes on our dvi.
If passed debug option to it via e.g. epstopdf --debug --gsopt=-dDEBUG
lyxpreviewjGIxTU.ps one gets:
Error: /typecheck in --div--
It seems related to hyperref, this page wrt preview+hyperref seems related
https://github.com/latex3/hyperref/issues/213
https://lists.gnu.org/archive/html/bug-auctex/2020-11/msg00000.html
I have no clue what 'latex shipout code' is and did not inspect further.
Apart from trying to figure out what's wrong with latex-preview I looked at
our sources and figured out that
1) although we see this error on console, the preview is still produced
OK via backup pdf route
2) this issue is not new to 2.4. It is present in 2.3 as well - the only
difference
triggering this problem in UG is:
-\default_output_format pdf2
+\default_output_format default
which was changed during 2.4 lifetime.
Given that the underlying problem is likely in latex-preview whose
maintainer is not interested in fixing (probably this) problem I would
leave the issue dormant.

Or using the attached for preview.
(Using this without problems for some time now)

The interaction between hyperref and preview has been present in LyX for
many years. I use preview more heavily than most and make a point of
leaving hyperref support off until final compilation. For instance, it
takes about 13 seconds for the previews in the documentation of a latex
package of mine to snap into view with the hyperref support checkbox
cleared, and about 33 seconds with it set. I have longer documents where
the difference is even more marked -- measured in minutes. When it's
set, a pdf containing every preview in the document is created in the
temporary directory. This doesn't happen when hyperref support is off.
If there was a solution, there would be one very appreciative user.
