Does the generic problem still exist? The one that you demonstrated with a sample image?

If the user loads an icon which has lines, the lines may disappear if the icon is scaled down. The problem could be seen with regular `ImageIcon` too, not necessarily with a `MultiResolutionImage`.

The solution is to apply BICUBIC rendering hint, which could be not as easy: the icon is likely used in a Swing component rather than rendered directly.
