JavaFX applications turning to "black screen" after some time

I see this too, also Windows 7.

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,
