Hmm. I figured this was just a me issue, but I see it's more prevalent. Does anyone know how we could launch the dialog from the terminal? It might give us an error message...

+1 Freshly installed from chaotic aur and it doesn't open

[mindo]

From the window decorations I cannot open it, but from the terminal it works just fine.

➜ grep -i exec /usr/share/kservices5/lightlydecorationconfig.desktop
Exec=kcmshell5 lightlydecorationconfig

➜ kcmshell5 lightlydecorationconfig

I get this output whenever I double-click on the Lightly option in kcmwindowdecoration to set the Lightly theme.

It updates the settings correctly, but I wonder if a KDecoration2::DecorationThemeProvider instance means the popup menu... IDK.

Same thing here. Will this be fixed or what?

➜ grep -i exec /usr/share/kservices5/lightlydecorationconfig.desktop
Exec=kcmshell5 lightlydecorationconfig

➜ kcmshell5 lightlydecorationconfig

After following @mindo's suggestion, running the command once fixes this issue. I can open the settings menu just fine even through System Settings as usual.
