KDE desktop icon labels - how to change from dark background to transparent?

Hi all, this might be a stupid question but I’m stumped. After installing openSUSE Leap 15.4 on several computers, my KDE desktop icon labels’ background became dark on one computer, as seen this this screenshot:

While on the other computers the icon labels’ background is transparent with shadow like this:

So, how do I change from the dark background to the transparent one? I went through the “Configure Desktop and Wallpaper” and “System Settings” tools and found nothing that seems to relate to this, and the right-click on the desktop background > “Icons” menu doesn’t have anything obvious either.

Help!

Strangely, after rebooting the machine the icon labels fixed themselves to have transparent backgrounds. Hmm. OK, I guess the problem is solved in mystery.

Hi,
On my old tumbleweed I can see those link, in my new tumbleweed I can’t see those link that was posted in this thread.
That’s weird.:frowning:
