Icons appear to be blurry on a Retina MacBook Pro screen

Running ..\..\gradlew run from apps/sampler-swing on a Retina MacBook Pro shows the demo browsing app, and all the icons appear to be blurry - instead of sharp.

I noticed that as well, it may be related to icon size and will have another look. Although the FontIcon class has the following code when creating the image where the icon is drawn

            Graphics2D g2 = (Graphics2D) buffer.getGraphics();
            g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
                RenderingHints.VALUE_ANTIALIAS_ON);

The icon is no longer blurry on HiDPI screens if it is painted directly to the Graphics object instead of painting it from the cached BufferedImage buffer.

Thanks! removing the double-buffering does solve the issue.
