How to disable the appearance change of an unfocused terminal window

Hi, I am using the terminal with the following settings for music visualisation:
"defaults":
{
"opacity": 50,
"padding": "0",
"useAcrylic": true
},

When a window is active, it looks like this:


When another window gets active, the terminal gets black. How can I disable this?
I was trying to play with the unfocusedAppearance setting in the terminal's settings.JSON, but it had no effect.



"profiles": {
"defaults": {
"useAcrylic": true,
"opacity": 50,
"unfocusedAppearance": {
"useAcrylic": true,
"opacity": 50
}
}
}
