    Description

      On XCB environment with following scenario

      • two running Qt applications
      • app1 is listening to QClipboard::changed()
      • app2 is setting the clipboard (e.g. with QClipboard::setText()) and then clearing the clipboard with QClipboard::clear()

      the signal QClipboard::changed() is not delivered in app1 for the app2's QClipboard::clear() change.

      Note: the signal QClipboard::changed() is delivered if the QClipboard::clear() is issued in the same app

      Expected behaviour: the signal QClipboard::changed() should be delivered no matter which application does the QClipboard::clear()
