SUMMARY

I'm not sure if this regression happened after updating to Plasma 6.1 Beta or if it's a regression caused by Qt 6.8.

When clicking on the next or prev buttons in the calendar applet, instead of moving just one month, it moves two or sometimes even more months.

It only happens on the calendar from the tray, on a widget in the desktop seems to work just fine.


STEPS TO REPRODUCE
1. Open calendar from tray
2. Click on next or prev month
3. Add calendar widget to desktop
4. Try the same on widget

OBSERVED RESULT
(See attached video)

EXPECTED RESULT
Jump one month at a time for each click.
