I'm running QT 4.4.0 and I'm having inconsistent behavior with the menu from my App Tray icon.
Randomly when right clicking my App tray icon the menu will appear with a random degree of transparency to the point where it's almost invisible.
Once the display issue occur, the menu will always show with the same transparency until restart of the App.
I could not find a consistent way to reproduce the issue but right clicking several times in a row the tray icon will eventually trigger this display issue.
I've seen it happen on XP and Vista.
Anyone seen a similar issue? Is it a know bug? Anything to prevent the issue?

Thanks
