Your display is configured to use 16 bit color (65 thousand colors). Surface selection assumes 24 bit color (16 million colors) where the code determines what cell/point is under each pixel.

Google search for color depth for your OS to determine how to increase and it will start working.

renWin->Render();
   int rgba[4];
   renWin->GetColorBufferSizes(rgba);
   if (rgba[0] < 8 || rgba[1] < 8 || rgba[2] < 8)
     {
     cout <<"Color buffer depth must be atleast 8 bit. Currently: " 
       << rgba[0] << ", " << rgba[1] << ", " << rgba[2] << endl;
     return 0;
     }
