David,
Have you tried to set your config.pro option for "Graphics"? By default it is 'OPENGL', but you can also try 'D3D' for DirectX or 'WIN32_GDI' for standard windows 32 bit graphics calls (win32_gdi is not recommended for production use, just for thesting) With the Radeon HD series, you might be better off using the DirectX option. Or change your graphics card to a FirePro or Quadro Professional Series that are made more for OPENGL use.
