As shown in the screenshots, when running the program, it does set the background correctly, but when I change the settings, only the background from the sliders get updated.
How do I make the background of the window itself change after the application has already started up?

You’re probably just missing a call to repaint to tell the component that it needs to be completely redrawn.
