OpenJFX only renders Parts of a Window when run on Ubuntu

Question

EDIT:

After some testing with options it turns out that when call: stage.initStyle(StageStyle.UNDECORATED) on the stage it resolve this problem of the window not showing, but then the window does not have controls. That means it might have to do with the window Manager and Controls.

ORIGINAL:

I am starting a JavaFX Stage with a Scene loaded from a FXML File using a FXML Loader.

This is a rather weird issue since no Exceptions or other form of error is displayed. Now only a part of the window gets rendered, shown here:

Here the Correct form as reference(Excluding the two entries in the ListView on the left):

Since i don´t get any errors i can only add information that might help resolve the problem.

JDK:

java version "11.0.1" 2018-10-16 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.1+13-LTS)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.1+13-LTS, mixed mode)

Tested on OpenJFX Versions:

1. 12-ea+4
2. 12-ea+2
3. 11.0.1

OS: elementary OS 5.0 Juno (Ubuntu 18.04 LTS) Graphics Driver: nvidia-390

CPU: I7 8700K GPU: GTX 1060 6GB

I tested it on a 4k screen, though i did changed the resolution to 1920x1800 and got the same result.

I can add as a note that after testing with multiple FXML files as source or simply a Alert, the rendered Size seams to always be the same .

Any Ideas on ways to solve this?

Answer 1

After a lot of testing it turns out its related to the Gtk Version. The used OpenJFX versions where accessing Gtk 3 and as a result created that bug, which could be resolved by calling: stage.initStyle(StageStyle.UNDECORATED) .

To actually fix the error its necessary to add the JVM Option: -Djdk.gtk.version=2 which completely solved the problem.

I will do more research on the source and add details here.
