Opengl Shader Color Fighting

[AustinJ]

I am passing color values to the shader through an buffer object in a vao. I intend for the color to be added to the texture color. What I am doing seems like it should work however it seems like I have z-fighting. The colors act as if there is z-fighting however the triangles are only being rendered once. The first image is what it looks like most of the time, however if I look down it looks like it should for the most part sometimes fighting when rotating the camera and such.

 

The game is made in C++ and OpenGL on Linux using the nVidia drivers. I am not sure what is causing this so if anybody has any ideas let me know.

 

Vertex Shader:

#version 450 layout (location = 0) in vec3 inVertex;layout (location = 1) in vec3 inCoords;layout (location = 2) in vec3 inNormal;layout (location = 3) in vec4 inColor; uniform mat4 projectionMatrix;uniform mat4 viewMatrix;uniform mat4 modelMatrix; out vec3 coords;out vec4 addedColor; void main(){gl_Position = projectionMatrix * viewMatrix * modelMatrix * vec4(inVertex, 1.0f);addedColor = inColor;coords = inCoords;}

 

Fragment Shader

#version 450#extension GL_EXT_texture_array : enable in vec3 coords;in vec4 addedColor; out vec4 out_colour;uniform sampler2DArray textures; void main(){ out_colour = clamp((addedColor + texture2DArray(textures, coords)), 0, 1);}

Is inColor constant or are you calculating new colors every frame?

It is computed when the chunk updates its model, so it is relatively constant.
