Hello Dragos, There are some known issues with Drag & Drop on Ubuntu from JavaFX11 as gtk3 has been made default. There is a bug filled for the same in JBS JDK-8211302. Drag & Drop does not work, but I don’t get the error you are getting. Can you please create a small reproducer to look at. For time being, you can use gtk2 by using -Djdk.gtk.version=2.
