How would one go about manually changing your icon theme? I've changed the Theme variable in kdeglobals, but don't know what else to do.

Is there perhaps a dbus command you can run?

If you logout and back in, or newly start a KDE application, is the icon theme change applied?

When I start a new application, the icon theme isn't changed at all, however when I log back out and back in, it changes about a third of the icons.

I've noticed when you change the icons in system settings it bring up a progress bar saying "Updating system configuration" so I assume after manually editing the kdeglobals there's a few commands that need to be ran or something needs to be restarted to apply this. However just restarting plasma-desktop doesn't quite do it.

I've checked the code in question and can't see anything that would have anything but an initial runtime effect - restarting applications should result in the new theme being fully applied.

The only part which is potentially relevant is the clearing of the "pixmap cache" although i'm not sure if this is referring to the "icon-cache.kcache" file at /var/tmp/kdecache-$USER/ or not. Does removing that file allow your manual change to complete after an application restart?

That worked perfectly! Thank you very much, I would've never thought to do that .
