Question

Compton can draw shadows under windows, which is nice, but unfortunately it draws shadows under the Gnome-Do window, which ends up like this:

Is it possible to keep that from happening?

Answer 1

• Add it to shadow-exclude array:

  # Shadow
  ...
  shadow-exclude = [ "class_g = 'Do'" ];
  

  in

  /home/<user>/.config/compton.conf
  

• Or specify it with compton launch command. Example:

  compton -c --shadow-exclude 'class_g = "Do"'
