This should fix it: https://github.com/kovidgoyal/calibr...c54c81d29ee883

In the next calibre release.

Thank you for your help and your work on Calibre !

What does the third stage of Check Library have to say for itself?

OK this has hit me. (I had split a 99cent Boxed set, populated the cover and metadata.

This is a GRID View issue. (I don't usually use that view, but happened to be looking for a book by Cover image )

The cover file is there. The cover shows in the MDE. The cover shows in Details.
IT does not show in Grid View.

It does not seem to be a VL issue as this is happening on the full library view as well as VL.
Both phases of the Library check pass with 'No Errors'

FWIW the books in question were added on 1 Feb 24 (in case this is a Leap Month issue)

I can't see a way to force a thumbnail rebuild

[BetterRed]

That's a known bug, here's the fix ==>> Grid view cover cache: Fix covers not loading when cache entries are stale

And here the threat that revealed the bug ==>> Covers disappearing in grid view but not in details book view

BR

[theducks]

FWIW I scrolled thru in grid view.
I only have 11 books with this issue. ALL were added on 1 Feb 2024

When calibre is not running, delete the cache folder AppData/Local/calibre-cache/gui-thumbnail-cache

I was looking there, but was leery because that is not normally backed up.

That fixed it. ... The Q is why did that happen (and only on a single day)
(I also do not (knowingly) allow (offsite) cloud store that I do not control

It happened because a) the cover was shown in the gui cover grid and therefore cached, and b) subsequently the cover file for the book changed its modified date without telling the GUI. Example: some external image editor. Example: copying the library without preserving mod times.

AFAIK Only Calibre operations (via GUI) has ever touched those.
I ran EPUB SPLIT (as I have many other times), Then later used the MDE to update the cover.


EPUBsplit uses a MDE style form just prior to 'done' to allow refined metadata.
The PI uses the 'source' cover (a boxed set image) as it has no clue if what I have split off has THAT cover (some do, some don't and a Bundle can only have 1 true cover'.

I tried a new thing, and updated the cover (used download cover button) before clicking OK
It did save the MDE cover,jpg, but maybe that is why the cached was messed up.
