The latest JDK5 update from Apple, JDK 1.5.0_19, reverted the default graphics renderer back to the Quartz renderer in 1.5.0_19 (they had been using Java2D by default). This causes significant artifacts when running JavaFX applications as described in RT-5008.

We have solved this problem in the javafx launcher script by setting the following flag to disable the Quartz renderer:

-Dapple.awt.graphics.UseQuartz=false

The following test program will show this bug if Quartz is used (i.e., if the UseQuartz flag is changed to "true"):

Stage {
    title: "Application title"
    width: 250
    height: 80
    scene: Scene {
        content: [
            ScrollBar {}
        ]
    }
}

EffectsPlayground also shows a problem where parts of the preview images "leak" outside the boxes.
