KDE Panel not changing color when switching between light/dark themes

Hi all,
Very recent convert. When I change my theme from light to dark it seems that the panel doesn’t change unless I log out and then log back in. Every other window switches to the light theme almost instantly. It’s only the taskbar that doesn’t change (until I logout/login).
I’ve searched the forum and google but I’m either using the wrong search terms or it’s something specific to my computer. Any guidance would be appreciated!

Are you talking about the panel ?


if so please edit the title kde task manager is kde system monitor

Try changing Plasma and icon theme

Issue resolved!

The Plasma Style seemed to still be stuck on the Breath2 Light theme, even though the Global Theme was Breath2 Dark. I changed the Plasma Style to match the Global Theme and the Panel now changes colour according to whichever Global Theme is applied.

Thank you both for your help–much appreciated!
