JavaFX applications turning to "black screen" after some time

[Danno Ferrin]

While we are playing "guess the bug" I'de like to jump in on the bandwagon.

Sometimes I see a white screen lockup on FX 2.2 on 7u25 (and all 7u for
that matter) when I dock and undock my laptop.  I've got one of those dell
laptops with a separate more powerful graphics chips in the dock.  It's
only the rendering that dies, the event loop executes just fine bringing up
the unsaved changes dialog and responding to (what are to me blind) clicks
on the controls.  I've seen this in SceneBuilder and int he embedded FX
panel in my corporate app.

New bug or old bug?
