Confirmed. But I'm not sure this is a bug in unity or in openjdk. Smaller code that reproduces this bug:
import java.awt.Color; import java.awt.GraphicsEnvironment; import javax.swing.JFrame; public class ScreenTest extends JFrame { ScreenTest() { setUndecorated(true); getContentPane().setBackground(Color.RED); setDefaultCloseOperation(EXIT_ON_CLOSE); setVisible(true); } public static void main(String[] args) { GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice().setFullScreenWindow(new ScreenTest()); } } ** Changed in: unity Status: New => Confirmed ** Also affects: unity (Ubuntu) Importance: Undecided Status: New ** Changed in: unity (Ubuntu) Status: New => Confirmed ** Summary changed: - Full Screen mode for Java Apps + Top panel is shown over full Screen window for Java Apps -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/898121 Title: Top panel is shown over full Screen window for Java Apps To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/898121/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
