We have upgraded from Qt 5.6 to Qt 5.6.2. After this, each dialog that is closed by clicking on a button produces this XCB error:
QXcbConnection: XCB error: 3 (BadWindow), sequence: 540, resource id: 14183585, major code: 40 (TranslateCoords), minor code: 0
When the dialog button is triggered by a key press, the XCB error does not occur.

Attached is a simple application that always produces this error message when I click the "ok" button of the message box.
