Lastly, pushed a change into gniibe/t7855 branch.
rGf861b2a33f96: gpg,gpgsm: Fix thinko for FP closing under no lock.

With the beta-25 the body of the mail is not saved back to the server any more but the security level tags are. So the test mail still seems to be a signed and decrypted empty mail even if you deactivate gpgol.

We did decrypt the mail successfully and called put_oom_string to update the Body successfully, but for some reason for new mails the put calls succeed but the displayed Text is not updated i.e. no "OpenGPG Message Please wait..." or decrypted message.
When closing the mail window the mail is still open in the preview pane and we should get back the mail content (Body), but we don't get back what we set with the put call but what is displayed i.e nothing (empty string).
So we pass on the close call which does write back our put value. (Plaintext leak)

Fixed. When one of the lists/tables gets focus then NVDA should speak something like "<name of list> list" or "<name of table> tree view".

I pushed further changes into gniibe/t7855 branch.
rG2fe62809014e: gpg,gpgsm: Serialize write access to keybox/keyring to protect.

Note: QGpgMEWKDLookupJob uses an Assuan transaction with dirmngr.

We had considered and rejected adding below the above configuration a marked section (like e.g. with a frame) showing the options in the order they appear in the sign/encrypt window:

• Sign as
• Encrypt for me
• Encrypt for others
• Encrypt with password
• Encrypt / Sign each file separately

We discussed this and decided that this would not be useful, as

I'm fixing this issue under T7855. So, I move this ticket as a child of T7855.

For remaining changes in 2.2, I pushed changes into gniibe/t7855 branch.
rGbd65b06b74c2: gpg,gpgsm: Don't lock recursively when KEEP_LOCK is enabled.
rG423fd047da87: kbx,gpg,gpgsm: Add FP-close method for keydb to close before unlock.
rG966258ac5f99: gpgsm: Fix delete and store certificate locking glitches.

I pushed changes into gniibe/t7855 for compressing the keybox.
rG8cc2a0e0ffee: gpg: Minor clean up for keydb_lock API.
rGe4d3c3aa2220: kbx,gpg,gpgsm: Introduce keybox_compress_when_no_other_users.
rG3e441d5b299f: kbx,gpg,gpgsm: More changes for compressing the keybox.

Then, we need to integrate following commits of 2.2 into gniibe/t7855 branch:
rG43fe9073aa81: gpg,gpgsm: Tweak the locking of the pubring.kbx
rG8491aca73cff: gpg: Revert the always locking introduced with 43fe9073aa
rGad4a5117ab1c: gpgsm: Properly release the lock when compressing a pubring.
rG7962eca3a023: gpgsm: Change delete and store certificate locking glitches.
rG22f9c4a3b3c1: gpg: Release lock after close also in the compress code path.

I created gniibe/t7855 branch for this issue.
To start with, I forward-port/cherry-pick 2.2 commits to the branch:
rG39430d9f78dc: build,common,g13,sm,tools: Require GpgRT 1.56.
rGe71aca2a628d: common: New function gnupg_remove_ext.
rGe38c5f7d5873: w32:common: Take care of possible race on startup under Windows.
rG7bfd37e305c0: common,w32: Always use share mode readwrite for the keybox.

@timegrid Thank you for your confirmation.

Sorry for my late review. I should have reviewed earlier.

Happens on vsd 3.3.2, too.

At which point did were you asked for the passphrase for decryption? You flushed the gpg-agent cache, right?

In pgp signed unencrypted text mails it happens, too, that first the "converted to plain text" message is shown without content, and after open/close the message is gone and the content is displayed.

I can't reproduce this in vsd-3.3.90.19 @ win10 anymore.
Probably the fixes in https://dev.gnupg.org/T7827 or https://dev.gnupg.org/T7855 solved this, too.
