This seems to be a good opportunity to replace paperkey with a new tool to take advantage of the smaller ECC keys which allow us to re-generate most stuff.

Ok, it was a missing update (although windows claimed to be up-to-date).
After installing 2025-06 [...] KB5060829 the Microsoft Print to PDF feature is available again and printing also works in Kleopatra/Okular.

A second patch fixes the problem with the button in the smart card view.

I have added a patch to disable recoloring of the status icons in Gpg4win. This ensures that the status icons in the selected rows don't get all-white.

Upstream bug report for invisible status icons: https://bugs.kde.org/show_bug.cgi?id=506434 (Icon coloring is inherently incompatible with colored Breeze status icons)

It's also the same error in Okular, when a pdf is printed.

Same on gpg4win-4.4.1 @ win11 (here a bit more debugview context)

Works fine here.

You're right, it also errors on gpg directly:

I can't reproduce. Please check whether this works if you use gpg directly; it's a bit unlikely that this is kleopatra-specific, since kleopatra doesn't really care whether the key is on a smartcard or not.

This only happens, if the smartcard key

• was used for sign/encrypt earlier and thus saved as selection default.

Not sure, what to expect, but generally looks fine for me in gpg4win-5.0.0-beta336 @ win10:

I guess, that's ok then, moving this to done.

Thanks, confirmed then, moving to Done.

Shouldn't the enabled close button in win10 / disabled text / nr2 have green color? (it's the "search certs on server" dialog).

Issue with pretty kyber names moved into: T7708.
Moving this to done.

General issues with unformatted fingerprints/keyids moved into T7707.

Any way to verify in kleopatra, that the setting was applied?

I guess that the missing formatting of fingerprint or key ID isn't restricted to v5 keys. -> separate ticket

Ingo tested this and it worked.

Looks good to me on gpg4win-5.0.0-beta336 @ win10:

• Full stops are fine now
• "not VS-NfD compliant" for invalid signatures not shown anymore (tested in vsd compliance mode)
