Describe your Bug

I noticed that LibreWolf/Firefox and other Apps still have a transparent background even when active_opacity/inactive_opacity is set to 1.0. This should be the maximum value per documentation.

Setting the value to more than 1.0 e.g. 2.0 makes the background of the apps opaque.

Reproduce

To better see the effect i disabled blur and shadows:

Still translucent:

decoration {
  blur:enabled = false
  shadow:enabled = false
  active_opacity = 1.0
  inactive_opacity = 1.0
  fullscreen_opacity = 1.0
}

Opaque:

decoration {
  blur:enabled = false
  shadow:enabled = false
  active_opacity = 2.0
  inactive_opacity = 2.0
  fullscreen_opacity = 2.0
}
