Apply PixDither to a duplicate layer. Then, set the blend mode of the original layer to and lower the opacity to 30%. This adds a secondary layer of noise that mimics dust on a CRT screen.
Do not download "PixDither Pro" from sketchy banner ads. The free version is fully featured; any paid version asking for $50 is likely a scam.
