Hi, For FXCanvas it should be doable because you can check if SWT is running with GTK3 using
----8<---- org.eclipse.swt.internal.gtk.OS.GTK3 : boolean ----8<---- This is what e(fx)clipse uses today to cancel loading of FXCanvas because it would core-dump your application [1]. IIRC this flag is there since the last SWT release!
