OBSERVED RESULT: Causing tasks to become independent solely causes their titles to disappear from the interface until Kontact is subsequently reinitialized. STEPS TO REPRODUCE: 1stly, invoke the contextual menu of any subtask. 2ndly, invoke "Make this to-do independent". EXPECTED RESULT: Each separated subtask should instantly appear above or beneath the parental task. SOFTWARE/OS VERSIONS Windows: Whether affected is unknown. macOS: Whether affected is unknown. Linux/KDE Plasma: Affected. KDE Plasma Version: 5.24.4 KDE Frameworks Version: 5.96.0 Qt Version: 5.15.5 ADDITIONAL INFORMATION I forgot to screenshot the window whilst this problem was present. Consequently, if it subsequently occurs, I shall provide pictography that depicts this problem. If this problem repetitively does not occur during subsequent separation, I shall file this report as "works-for-me" or remediated.
I can't reproduce this in newer KOrganizer (I tested version 6.4) I'll close this. feel free to reopen if it still happens for you in newer KOrganizer versions.
(In reply to Allen Winter from comment #1) I'd like to re-test, but when I click "Add a calendar...", all I see is Knut. Additionally, https://bugreports.qt.io/browse/QTBUG-135786 renders adding an account via systemsettings impossible (if that even affects KO). Apologies; if I've ever a chance to test, I'll check again, but I shan't be able to for some time, it appears.
