Description Attila 2025-07-24 06:53:50 UTC

SUMMARY

KMail shows in the left panel (for example) 49 new e-mails in the inbox, but only 3 new e-mails appear in the message list. It's not predictable when this happens, but it happens at least once a week. KMail requires a restart to display all new e-mails.

STEPS TO REPRODUCE
1. Open KMail
2. Get the new e-mails
3. Compare the number of new emails displayed in the left panel with the number of new emails displayed in the message list

OBSERVED RESULT
It is not possible to read all new emails when the bug occurs.

EXPECTED RESULT
KMail should display all new e-mails in the message list.

48 new e-mails, not 49. Sorry for the typo.
