Window opening glitch on ubuntu 18.04

[Thiago Milczarek Sayão]

I have migrated our development environment from java-10 javafx to
java-11 and openjfx-11.

One thing I have noticed is that windows opens on the top left corner
of the screen and than moves to a center location. The weird thing is
that we can see the window moving. It appears to be a glitch.

This also happened on java-10 with the bundled javafx when setting it
to use gtk-3 instead of gtk-2.

So it appears to be a gtk-3 bug/glitch.

We use x.org (not wayland).

Someone reported a similar issue with a differrent Linux distro (Manjaro
17.1.12) also related to GTK 3:

I'll file a JBS bug for this. In the mean time, you can add a comment to
the above GitHub issue if you like.

And this was reported even earlier at:

https://github.com/javafxports/openjdk-jfx/issues/129

also with Ubuntu 18.04. I have added a pointer to both in the JBS bug.

I have not noticed this on OpenSUSE Leap 15. The window pop up right in the
center of my screen in an instant.
NVIDIA graphics with NVIDIA proprietary drivers.

Running my modular test application on Java 11 and JavaFX 11.

I did however noticed for a split second that a dialog I opened was in the
upper left corner. It was hardly noticeable.
