Don't use qDebug for formatted output - but QDebug is ok

That's the difference between readable output and unreadable mess.

Good:
QPlatformSurfaceEvent(surfaceEventType=SurfaceCreated)
QEvent(WinIdChange, 0x7ffdadee2bd0)
QEvent(WindowIconChange, 0x7ffdadee2d30)

Bad:
[351295.324] qev(88029 88029)(Widget::event|QApplicationPrivate::notify_helper|QApplication::notify|QCoreApplication::notifyInternal2|QCoreApplication::sendEvent|?libQt5Widgets.t.so.5?|QApplicationPrivate::notify_helper|QApplication::notify|QCoreApplication::notifyInternal2|QCoreApplication::sendEvent):
        QPlatformSurfaceEvent(surfaceEventType=SurfaceCreated)
