Recently i started using X3 in trial version. After making some initial setup i uploaded some logo picture in .png format. After uploading and refreshing the site the logo looks terrible: transparency is not smooth and gradient part of the logo present horrible banding.

Note, that this happens when browsing on my Mac using chrome as well safari. On my iPhone & iPad everything looks great.
What can be the reason?
