JavaFX applications turning to "black screen" after some time

[John C. Turnbull]

Hmm, I am not sure that is the same issue.  That issue seems to be related
to artefacts appearing after screen lock but what I am seeing is a totally
black window and it doesn't need a locked screen to make it happen.

And at least for me, I have never seen this with Scene Builder although I
note that you have observed this.

Seems to be related to this issue:
https://javafx-jira.kenai.com/browse/RT-30362

And no, unfortunately Scene Builder is not always immune to this, I got it
with SB regularly

HTH,
