Question by kvark · Mar 05, 2011 at 11:36 PM · custom-shaderglsl

Weird GLSL behavior

Hello,

I have a simple GLSL program:

        varying highp vec3 normal;
        #ifdef VERTEX
        void main() {
            normal = gl_Vertex.xyz;
            gl_Position = ftransform();
        }
        #endif
        #ifdef FRAGMENT
        void main() {
            gl_FragColor = vec4(normalize(normal),1.0);
        }
        #endif

When used on an object, I can see flickering of the color change when moving and rotating the camera in the editor. What am I doing wrong?

Screen-1 Screen-2

Environment: OS X 10.6.6, MacMini 2010 model

Edit-1. Shader compiles and links correctly (at least Unity doesn't report errors/warnings).
