From the developer:
Create an ICNS file from that icon you just made, free. ICNS files store different sizes of icons, to make them look better at smaller sizes. Edit your icon down to 16x16, and put that in the smallest spot. This way, the computer switches to that icon rather than render a 128x128 icon down that small.
