Chat GPT bug. Repeat same line over and over

I was asking GPT for some help on some code and it ended up in a loop where it just repeated the same line over a hundred times until it ran out of tokens. I then hit the continue generate button and it kept repeating it. Not really a major issue but maybe it will help the OpenAI team. Here is how the conversation went:

Me: how could I create a shader in unity that overlays a color on the whole screen?

Chat GPT: To create a shader in Unity that overlays a color on the whole screen, you can use a simple fragment shader. Here’s a basic example using Unity’s ShaderLab language:

// Shader “Custom/ColorOverlay”
Shader “Custom/ColorOverlay” {
Properties {
_Color (“Overlay Color”, Color) = (1,1,1,1)
}

SubShader {
    Tags {"Queue"="Overlay" }
    Pass {
        CGPROGRAM
        #pragma vertex vert
        #pragma exclude_renderers gles xbox360 ps3
        ENDCG
        SetTexture[_Dummy] {
            combine primary
        }
    }
}

SubShader {
    Tags {"Queue"="Overlay-1" }
    Pass {
        CGPROGRAM
        #pragma vertex vert
        #pragma exclude_renderers gles xbox360 ps3
        ENDCG
        SetTexture[_Dummy] {
            combine add
        }
    }
}

}

// Upgrade NOTE: replaced ‘_Color’ with ‘_Color0’
// Upgrade NOTE: replaced ‘_Color’ with ‘_Color0’
// Upgrade NOTE: replaced ‘_Color’ with ‘_Color0’
// Upgrade NOTE: replaced ‘_Color’ with ‘_Color0’

NOTE: It kept repeating the line above hundreds of times
