Did the system go into screen lock during that time? If so, then this is:

Otherwise it sounds like a new bug.

I am not sure if it is a known issue but any JavaFX application I run and

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?
