Description Patrick Silva 2022-06-13 15:09:23 UTC

STEPS TO REPRODUCE
1. open Fonts KCM
2. click on 'Adjust all fonts...' button
3. choose another font - I changed from default Noto to Zekton on my system
4. apply the change

OBSERVED RESULT
the new font is applied to System Settings, but Plasma (icons on desktop, popups and context menus) is still using the previous font. The chosen font is used after restarting Plasma with 'plasmashell --replace'

EXPECTED RESULT
the chosen font should be immediately applied to Plasma

Weirdly i can reproduce again. As we can see in the attached screenshot, the font applied in the KCM is immediately applied to Digital Clock widget, it's partially applied to System Settings and is not applied to Kickoff and widgets on desktop until Plasma is restarted.

Fonts of the title of systray applets and Holidays section of the Digital Clock are not immediately update after changing the font in Fonts KCM.
