I have a clutter actor and I need it to be painted without transparency. I can get the background color and set alpha to 255, but that doesn't work with background images or border images. They are defined through CSS by the user, so I can't just edit them.
What I currently do to remove the background-color alpha:
let color = actor.get_background_color();
color.alpha = 255;
actor.set_background_color(color);
I am not who writes the actor. I'm a user of the actor so I can't rewrite its paint methods. Any way to flatten it?
