OpenGL Nvidia Driver 259.12 texture not working

My OpenGL application which was working fine on ATI card stopped working when I put in an NVIDIA Quadro card. Texture simply don't work at all! I've reduced my program to a single display function which doesn't work:

void glutDispCallback()
{
//ALLOCATE TEXTURE
unsigned char * noise = new unsigned char [32 * 32 * 3];
memset(noise, 255, 32*32*3);

glEnable(GL_TEXTURE_2D);
GLuint textureID;
glTexEnvi(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_DECAL);
glGenTextures(1, &textureID);
glBindTexture(GL_TEXTURE_2D, textureID);
glPixelStorei(GL_UNPACK_ALIGNMENT, 1);
glPixelStorei(GL_PACK_ALIGNMENT, 1);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST);
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, 32, 32, 0, GL_RGB, GL_UNSIGNED_BYTE, noise);
    delete [] noise;

//DRAW
glDrawBuffer(GL_BACK);
glViewport(0, 0, 1024, 1024);
setOrthographicProjection();
glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );
glLoadIdentity();
glDisable(GL_BLEND);
glDisable(GL_LIGHTING);
glBindTexture(GL_TEXTURE_2D, textureID);
glColor4f(0,0,1,0);
glBegin(GL_QUADS);
    glTexCoord2f(0,0); 
    glVertex2f(-0.4,-0.4);

    glTexCoord2f(0, 1); 
    glVertex2f(-0.4, 0.4);

    glTexCoord2f(1, 1); 
    glVertex2f(0.4, 0.4);

    glTexCoord2f(1,0); 
    glVertex2f(0.4,-0.4);

glEnd();
glutSwapBuffers();

//CLEANUP
GL_ERROR();
glDeleteTextures(1, &textureID);
}

The result is a blue quad (or whatever is specified by glColor4f()), and not a white quad which is what the texture is. I have followed the FAQ on OpenGL site. I have disabled blending in case texture was being blended out. I have disabled lighting. I have looked through glGetError() - no errors. I've also set glTexEnvi(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_REPLACE); and GL_DECAL. Same result. I've also tried different polygon winding - CW and CCW.

Anyone else encounter this?

Any reason you're creating/destroying a texture object every frame instead of just uploading new texture data? - genpfault
It's just some code to replicate the problem. I don't do that in reality. - Budric

Can you try using GL_REPLACE in glTexEnvi? It could be a bug in the NV driver.

Your code is correct and does what it should.

memset(noise, 255, 32*32*3); makes the texture white, but you call glColor4f(0,0,1,0); so the final color will be (1,1,1)*(0,0,1) = (0,0,1) = blue.

What is the behavior you would like to have ?

I found the error. Somewhere else in my code I had initialized a GL_TEXTURE_3D object and had not called glDisable(GL_TEXTURE_3D);

Even though I had called glBindTexture(GL_TEXTURE_2D, textureID); it should have bound a 2D texture as the current texture and used that - as this code always worked on ATI cards. Well apparently the nVidia driver wasn't doing that - it was using that 3D texture for some reason. So adding glDisable(GL_TEXTURE_3D); fixed the problem and everything works as expected.

Thanks all who tried to help.
