+1 I see this too, also Windows 7.

September 2013 07:55 An: openjfx-dev@openjdk.java.net Betreff: JavaFX applications turning to "black screen" after some time I am not sure if it is a known issue but any JavaFX application I run and then leave minimised for some time (say 15mins+) and then restore will have an entirely black window with nothing actually visible. This is on Windows 7 and Scene Builder curiously seems to be immune to this problem. Any ideas why this is happening? It looks like an off-screen buffer being lost (as it resembles the behaviour I used to see with Swing VolatileImage when the contents were lost)? Is there any way to programmatically avoid this? Thanks, -jct
