Could you review the updated fix:

There are two places where D3DSurfaceData.swapBuffers() is called 
D3DScreenUpdateManager.run() and D3DGraphicsConfig.flip(...).
D3DScreenUpdateManager.run()  uses the surface bounds which are already 
D3DGraphicsConfig.flip(...) uses coordinates in the user space.

The fix converts the coordinates in the D3DGraphicsConfig.flip(...) to 
the device space and converts the coordinates to the user space in the 
D3DSurfaceData.swapBuffers() method to pass them to the repaint() method.
