Created attachment 139382 [details] screenshot of reminders I did just a system upgrade on openSuse Tumbleweed and after reboot and a new login, the reminder daemon pops up the dialog showing me dates from 3 weeks ago. See screenshot. I expect to not see reminders for dates which have already long passed. Operating System: openSUSE Tumbleweed 20210614 KDE Plasma Version: 5.22.0 KDE Frameworks Version: 5.82.0 Qt Version: 5.15.2 Kernel Version: 5.12.9-1-default (64-bit) Graphics Platform: X11 Processors: 4 × Intel® Core™ i5-6300U CPU @ 2.40GHz Memory: 15,5 GiB of RAM Graphics Processor: Mesa DRI Intel® HD Graphics 520
Is this repeatable? If you press "Dismiss All" and reboot, does the daemon still pop up a list of old notifications? Are events and reminders that you entered recently still present in the calendar?
Sadly, I can not reproduce it. I tried to logout several times, ensuring no processes were running for my user, then login again - no reminders. Event after a reboot (although I'm pretty sure that does not make any difference) and login, no reminders. I had the issue already a few times in the past, but since I very seldomly logout or even reboot (every few weeks only), the chance is therefore already rather low.
As of version 22.04.0 (5.20.0), korgac has been replaced by a new reminder daemon, kalendarac. If you have upgraded to that version, please watch for unreliable reminders and report them as bugs for product "Reminder Daemon". Perhaps the system upgrade damaged the files where korgac stored its records of dismissed reminders.
