问题
I'm currently building an application with OpenJDK 11 and OpenJFX. It compiles just fine, and starts, but there is no titlebar, and if i click close to the edge of the app, it registers as a click on whatever window is behind it.
I am using intelliJ idea, and it took a while to figure out how to even use openjfx with it, anyhow, here's the system details:
running elementary OS 5.0 Juno (based off of Ubuntu 18.04, everything is GTK) IntelliJ Idea (Community) 2018 installed as a snap. OpenJFX sdk downloaded from here: OpenJFX from Gluon
I've just made a new javaFX app, and added the dir /javafx-sdk-11.0.1/lib/ to external libraries, and then went to run -> edit configurations and added vm options --module-path <path>/javafx-sdk-11.0.1/lib --add-modules=javafx.controls,javafx.fxml,javafx.base
controller and everything seems to work, but the resulting window looks like this:
Does someone know just what i'm doing wrong here?

Thanks to José Pereda
It was exactly that which fixed it. See the question he linked for details: problems with gtk3 and javafx
Anyhow, in intelliJ it's solved by going to Run -> Configurations and adding -Djdk.gtk.version=2
to the 'VM Options'
