Yes make sure you disable "Optimize Quantizers" to get rid of that strange artifact. The game should play perfect besides that.
Make sure you use the OpenGL plugin as it is much more accurate and compatible. Also I am not sure about the DolphinIL.exe however I noticed disabling "Idle Skipping" for me increased performance on animated backgrounds, such as the one in the mansion entrance when you come down the stairs and the candle flame is directly in front of the camera.
