The resolution is obviously wrong and some fractal pixels are displayed in areas were colors are changing.
Some customers need a better result here.
(our competitor 3Dvia Composer creates better results)

Similar idea here: Add png as a save as file type
pngs are better suited for graphics than jpgs are. FYI - TIFFs are supported so you could always use those and your images will look better.
