I’m currently using a Viewport to display the game window in the center of the screen. Without the above shader being applied, everything looks as it should. But when I apply the shader to the viewport container it ignores whatever is in the viewport and only shades the wallpaper instead.
How do I get the shader to apply to the game window content?
Whats’ ignored? What is a “wallpaper”? It’s quite unclear what’s happening. Central part looks shaded.
Can you provide another picture demonstrating an issue (and a scene structure)?

This is the screen without the shader applied. The wallpaper is the image behind the actual game viewport. (I wanted something other than just straight black behind the game when running fullscreen). When I apply the shader, it doesn’t apply to the actual image in the center.
