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.

JavaFx 12 got issues with drag&drop on Ubuntu.
(java:3346): GLib-GObject-WARNING **: 13:50:41.198:
../../../../gobject/gsignal.c:2523: signal 'expose-event' is invalid for instance '0x7f43343c6520' of type 'GtkWindow'

Is this something known ?

Thank you,
