Systray and menu bar integration.

Unity installs a plugin for Qt (platformtheme plugin) that redirects some of 
the X11 calls into those specific to Unity. Though I think the systray 
(notification) integration is now moved into Qt's own XCB plugin, with no need 
for the platformtheme plugin to do it.

I also think Ubuntu carries patches to Qt that redirect some of the 
functionality. Those patches have been responsible for breaking some Qt 
applications -- for example, some were shown with no menu bar, either inside 
the window or Mac-style in the top bar.
