flashing transition

Hi all,

I'm having a problem with a transition.

In my application, I have 2 states, one containing a HBox with a Panel inside, and one with only a custom component in it.

As you can see in the code below, I defined a transition between loginState and reservationState, which uses an Iris effect

to hide the loginScreen, followed by a Fade effect which fades in the reservationScreen.

This all works as expected, but right before the Iris effect starts, the loginScreen disappears for a brief moment.

I hope someone cna point out what it is I'm doing wrong.

Best regards,

Jurgen
