Controlling transparency of drop-down menus

[sivvak]

I'd like to make menus like this one in Dolphin less transparent. I'm using Better Blur + Kvantum + Ant-Dark theme.
Is this easy to do and if so, should I tweak it in Kvantum config? Or somewhere else?
Changing the blur strength in the Better Blur settings doesn't seem to affect this 😅

I don't know how your theme has made it translucent, but I succeeded in making combo completer popups translucent by using reduce_window_opacity= and giving a translucent color to base.color=. They're blurred here.

I don't have Dolphin and don't intend to install it (lots of extra dependencies). I use LXQt+kwin_wayland.

BTW, programmatically, it's Qt's built-in popup for combo-box's completer, not a menu. If Dolphin uses what Qt provides (and not a handmade popup), it should get blurred when you've enabled blurring.

Changing the opacity in base.color to FF allowed me to get a non-transparent effect. I'm wondering what other things this will affect 🤔

Actually, it isn't good practice to give a too translucent color to base, because some apps may do weird things — not Qt's or Kvantum's fault though.

The window SVG element (its name may be under [Window]), if any, and reduce_window_opacity.

What I don't understand is why it isn't blurred in your case.
