    Question texture disappears!

    I load a HDR image as a texture and I wrote shaders to map the 2 texture to a sphere but texture disappears when I click on it or when I resize the window! Here is my code for display function:
    Code:
    void Draw()
    {
      qobj = gluNewQuadric();
      gluQuadricTexture(qobj, GL_TRUE);
    
      model->GetFaces();
    
      glEnable(GL_CULL_FACE);
    
      glFrontFace(GL_CW /* or GL_CCW */ );  //default is GL_CCW
      glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    
    
    
      glLoadIdentity();
    
      glPushMatrix();
      glTranslatef(tx, ty, 0);
      glRotatef(rotx, 1, 0, 0);
      glRotatef(roty, 0, 1, 0);
    
      LShader.bind();
      glEnable(GL_TEXTURE_2D);
      glActiveTexture(GL_TEXTURE0);
      glBindTexture(GL_TEXTURE_2D, texture);
      gluSphere(qobj, 1, 30, 30);
      int texture_location =
          glGetUniformLocation(LShader.GetID(), "color_texture");
      glUniform1i(texture_location, texture);
    
    
    
      gluDeleteQuadric(qobj);
    
      glDisable(GL_TEXTURE_2D);
    
    
      LShader.unbind();
      glPopMatrix();
      glutSwapBuffers();
    };
    Thanks in advance
