Looks good to me. +1

I'll test later today on Ubuntu 14.04 as well.

Yes, it works perfect for Ubuntu 14.04 & 16.04 right after the fix. For some reasons Ubuntu 16.04 requires double buffering on.

Code looks clean and works just fine on my Ubuntu 16 with gtk 2 & 3. Did you have a chance to test this on your Ubuntu 14 ? If we are good to go, I can push Thursday.

Hi David, I have different wrong window appearance in my instance of Ubuntu 16.04. GTK3 3.22 got paint changes which affect JFX paint. Some paint functions we use are deprecated since 3.22 but they should still be functional. Probably this is a GTK bug. I found that I can fix my Ubuntu 16.04 issues by the next patch: http://cr.openjdk.java.net/~ssadetsky/8171330/webrev.01/ Please test it on your env.

Adding a selection of off behavior. Good is the expected. Oddbad took the foreground of the active Screenshot app. bad show a translucent "empty" area Both of the bads started as rectangular, but switched to circular when I started to take a screen shot.

Thanks, David. I confirm that it doesn't work for Ubuntu 16.04 sometimes, but works for 14.04 always.

Ouch. There is something else going on here, but I am not sure what yet. With your .00 change, and using: javafx -Djdk.gtk.version=3 -Djdk.gtk.verbose=true -cp Hello/dist/Hello.jar hello.HelloTranspStageAnim I rarely seeing the application not quite display. I see a translucent background square, but not the rounded stage I should be seeing. This is onto a Ubuntu 16 display. Trying to debug now...
