JavaFX applications turning to "black screen" after some time

[John C. Turnbull]

I notice this issue even with FX 8 applications and b106.  And when the
issue occurs it doesn't matter how long I wait, the window stays black
permanently.

Again though I have never seen this with Scene Builder so it seems
individual results vary.

And I realize you are certainly on Fx 2.2, since although we are working
hard on it, SB on Fx 8 is not yet avalaible :-)
RT-30362 is specific to Fx 8.0

Using SB 1.1 (so Fx 2.2), I also notice your issue (entirely black
window) on Win 7 when SB is minimized for a while, then restored.
Generally the window  come back to a normal state after few seconds,
sometimes more (around 1mn).

I think this deserve a new Jira (for reference), I don't think there is one
related to that for Fx 2.2.

Thanks
Jerome
