I just upgraded to F43 from F42 and find that all my widgets in the system tray are now invisible. I can use them if I hover my mouse over them, but I can’t see them. Not a show stopper, but would be really nice to be able to go to exactly the one I need instead of hovering over them one by one.
I have upgraded two machines with KDE Plasma from 42 to 43, and this didn’t happen on them.
Have you tried changing the theme or dark mode? One thing I could imagine is that KDE ended up in a situation where it renders light (dark) icons on a light (dark) panel, essentially making them invisible.
Or do you use a custom theme? I have seen quite a few reports here about issues with custom themes.
I am not using a custom theme. I have noticed, after playing around a bit, that when I go to add/remove widgets, none of the widgets, except a few, have an icon showing.
Oh, and now they’re all back! I literally did nothing other than poke around in system settings for themes. When I exited it asked if I wanted to save the unsaved changes. I said “yes” and now they’re back! Grrrr.
