Created attachment 5534 Shows a square appears on the top-left corner of the screen Found in versions Xfwm 4.10.* 4.11.* A square appears on the top-left corner of the screen, when composite is ON and java-app with tray icon. There's a screenshot attached that shows the problem.
Looks like the (default, empty) icon of your app, hardly a major issue as stated in the severity of the bug.
The BUG is known. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=667682
Simple example: <code> import java.awt.Image; import java.awt.SystemTray; import java.awt.Toolkit; import java.awt.TrayIcon; public class IconTest { public static void main(String args[]) { TrayIcon trayIcon = null; if (SystemTray.isSupported()) { SystemTray tray = SystemTray.getSystemTray(); Image image = Toolkit.getDefaultToolkit().getImage( "/usr/share/pixmaps/sun-java.png" ); trayIcon = new TrayIcon(image); try { tray.add(trayIcon); } catch (Exception e) { System.err.println(e); } } } } </code> and in terminal: javac IconTest.java java IconTest
(In reply to trash4inbox from comment #3) > Simple example That's the icon in the systray, not the window icon, the window manager does not manage this.
May be. But without composite isn't the square on the top-left corner of the screen and isn't the square within another window manager (compiz).
Hi, I have the same artifact on top left corner with SelekTOR java application. Here is a Screenshot: http://i.imgur.com/HRp66Yy.png $ lsb_release --all No LSB modules are available.
