    Description

      Extra empty lines in Debug windows appears starting from 4.7.0 (4.6.2 seems fine).

      Attached is empty Qt-widgets project wheere I only added

      qDebug() << "Test";
QThread::sleep(3);
qDebug() << "Test";

      in main.cpp

      As the result of "Run" under QtCreator4.7.0 I see in the "Application Output" window strage "gap" between to "Test"s:

      Test













Test

      And I see expected output

       

      Test
Test

       

      in QtCreator 4.6.2

      Extra lines appears sequentially with period about 0.5-1 sec. So if one change sleep(3); to sleep(5); the gap will be larger! There is some kind of timer appearing from nowhere and influencing Application Output window?
