Qt 5.3 QSystemTrayIcon not working correctly[Linux]

so I wrote some Qt5 application and wanted to add a system tray icon with QSystemTrayIcon. After being done with coding I compiled and ran it and a system tray icon did not appear, so I tested around, added a line so it would display a info bubble, which it did, but in the top left corner, instead of in the system tray.

Anyway I tried Qt4.8, compiled the same code and there it worked just fine.

I'm using Arch linux with latest updates, XFCE4 as DE and Qt 5.3.0-3. I made the application with Qt Creator.

I wrote an example application which has the same behaviour. So here's the code:

MainWindow.h

#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>
#include <QSystemTrayIcon>
#include <QIcon>
#include <QMenu>

namespace Ui {
class MainWindow;
}

class MainWindow : public QMainWindow
{
    Q_OBJECT

    QSystemTrayIcon *trayIcon;
    QMenu *trayMenu;
public:
    explicit MainWindow(QWidget *parent = 0);
    ~MainWindow();

private slots:
    void on_pushButton_clicked();

private:
    Ui::MainWindow *ui;
};

#endif // MAINWINDOW_H

MainWindow.cpp

#include "mainwindow.h"
#include "ui_mainwindow.h"

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);

    trayMenu = new QMenu(this);
    trayMenu->addAction("Test");

    trayIcon = new QSystemTrayIcon(this);
    trayIcon->setIcon(QIcon(":/ui_conf.png"));
    trayIcon->setContextMenu(trayMenu);

    trayIcon->show();
    trayIcon->showMessage("Well...", "Here I should be I guess?");

    ui->pushButton->setIcon(QIcon(":/ui_conf.png"));
}

MainWindow::~MainWindow()
{
    delete ui;
}

void MainWindow::on_pushButton_clicked()
{
    this->close();
}

main.cpp

#include "mainwindow.h"
#include <QApplication>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
    w.show();

    return a.exec();
}

Thanks in advance!

it's a regression (bug) on Qt 5.x versions. Here is the bug record for it https://bugreports.qt.io/browse/QTBUG-31762 it's still open :(

You can try gtk code in your Qt app to create a working system tray icon/menu.

The code looks solid to me, but it looks like there are problems with QSystemTrayIcon in certain Linux distros. Check out this link for more info: http://www.qtcentre.org/threads/56459-QSystemTrayIcon-and-linux
