Duplicate Rendering Issue with Spotlights Using BackBufferCopy and Color Dodge Blend Mode

Godot Version 4.3

Hi everyone,

I’m working with two 2D spotlight nodes in my project, and I’ve applied the Color Dodge blend mode to both of them. Since they both have transparency, I’m using a BackBufferCopy node to make the effect work properly. However, I’ve encountered an issue where the spotlight on the right is being rendered twice, causing it to appear brighter than it should.

Does anyone know how I can solve this issue?
Thanks for any help or suggestions!
