Thanks, I'm fairly sure it is the same issue... I'll update the bug with
these details too.

Attached is my test code that reproduces the problem. It shows 3
rectangles in red, green, blue going "into the page", i.e. with red at
front. The mouse can be dragged up and down to rotate the shape.
This renders correctly as native JFX Application but when in a JFXPanel
the green and blue rectangles "show through" the red rectangle.
The attribute "embedded" controls if the scene is embedded in a JFXPanel
in a JFrame or is "native" JFX Application.

I've reproduced problem on both my work PCs
PC 1: Win XP, with JFX 2.0.1
PC 2: Win 7, with JFX 2.0.2

Console outputs (with -Dprism.verbose=true -Djavafx.verbose=true)

embedded = true for PC 1 (Win XP, with JFX 2.0.1)
