QtCreator 4.9.2 on KDE Manjaro 18.0.4 Illyria does not print debug messages

Hello,

I am programming on Manjaro 18.0.4 Illyria using QtCreator. However, it doesn't print the debug messages on the Application Messages pane.
The same source code with the same .pro file works fine on Ubuntu and Windows. It prints the
qDebug() << "Messages"
just fine.

What is Manjaro doing differently to prevent QtCreator and the application being debugged to show debug messages on QtCreator Application Messages pane?
