Details

Description: When calling show() on a QSystemTrayIcon while the traybar isn't available will hide the tray icon forever. The trayicon won't come up, if there's a traybar started some time later.

Also the description of QSystemTrayIcon says, this should work:

If the system tray is unavailable when a system tray icon is constructed, but becomes available later, QSystemTrayIcon will automatically add an entry for the application in the system tray if the icon is visible.

It started to appear with Qt 5.12. This wasn't the case when using the Qt 5.11 versions.



Additional info:
* Affects v5.12.x
* Upstream: https://bugreports.qt.io/browse/QTBUG-73459


Steps to reproduce:

Kill your traybar (however you do it).
Launch an application, which uses a QSystemTrayIcon
Start your traybar again.
The app's icon won't show up.

The bug is arguably even worse, because tray icons vanish if the tray becomes unavailable intermittently. Which can happen during display reconfiguration.

So every time a new display is added or reconfigured one has to restart Qt5 applications.

Please consider consider to apply the fix.

Can the priority on this be bumped way high, please? It has max priority on the Qt bug tracker.

Hello, the final patch was released and the fix will be available in 5.13 and 5.12.4.
