Set picom to NOT use tranparency

[se7en-x230]

I would want to setup picom with rounded corners and some of the window fading effects BUT NO transparency.
I fail to understand how to archive that.

picom itself doesn't add any kind of transparency (unless it's configured to do so with, for example, the opacity-rule option or the picom-trans command line utility), it just allows windows that request transparency to be transparent. you have to configure desired applications to not request transparency.

Check your ~/.config/picom.conf for keyword "opacity".

For example setting

popup_menu = { opacity = 1; }
dropdown_menu = { opacity = 1; }

or completely removing those lines disables opacity for certain windows.
Some distributions could have preconfigured opacity for other windows.
