SUMMARY

In a Plasma Wayland session, the Digital Clock calendar popup incorrectly shows “No events for today” the first time it is opened after login, even when events exist. Interacting with the calendar immediately causes today’s events to appear.

This occurs consistently on first open after login.


STEPS TO REPRODUCE
1. Click the Digital Clock in the Plasma panel
2. Click on calendar date

OBSERVED RESULT
The calendar displays "No events for today."  


EXPECTED RESULT
The calendar should display today's events. 


SOFTWARE/OS VERSIONS

Linux/KDE Plasma: 
KDE Plasma Version: 6,5,4
KDE Frameworks Version: 6.22.0
Qt Version:  6.10.1

ADDITIONAL INFORMATION
If I click another date, the calendar shows the events for that day,. If I then click back on the current date the calendar shows the day's events correctly.  The calendar should show the day's events the first time the date is clicked without first requiring the user to click on a different date. 

According to chatgpt this issue arises because: 

"The calendar widget relies on Akonadi to supply events. On first invocation after login, the widget UI is shown before Akonadi reports readiness. The widget queries for "today’s events” too early.
Result: it renders “No event for today”. Any interaction (clicking another day) triggers a refresh, and by then Akonadi is ready — so events suddenly appear. This is a race condition, not a logic error."
