here is a very simple example where the problem is very easily recognizable.

package net.vidux.test;

import org.eclipse.jface.dialogs.MessageDialog;
import org.eclipse.swt.SWT;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Event;
import org.eclipse.swt.widgets.Listener;
import org.eclipse.swt.widgets.Shell;

public class SWTTestFullScreenDialog {

	public static void main(String[] args) {
		Display display = new Display();
		final Shell shell = new Shell(display);
		shell.setLayout(new GridLayout());
		Button openDialog = new Button(shell, SWT.NONE);
		openDialog.setText("Open dialog");
		openDialog.addListener(SWT.Selection, new Listener() {
			public void handleEvent(Event arg0) {
				MessageDialog.openInformation(shell, "Info Title", "Info message");
			}
		});
		shell.open();
		shell.setFullScreen(true);
		while (!shell.isDisposed()) {
			if (!display.readAndDispatch())
				display.sleep();
		}
		display.dispose();
	}
}

I cannot reproduce this issue on GTK3.22/4.8 M7/Fedora 28.
