[Interest] xcb: moved mouse to .... spamming console

[Guido Seifert]

Hi,
just discovered in one of my ancient programs.
Linux/Qt 5.5

Whenever I move the mouse in a widget, I get console output like this:

> qt.widgets.gestures: QGestureManager:Recognizer: ignored the event:  QPanGesture(state=Qt::GestureState(NoGesture),lastOffset=QPointF
> (0,0),offset=QPointF(0,0),acceleration=0,delta=QPointF(0,0)) QEvent(Leave, 0x7fff83652e10, type = QEvent::Type(Leave))
> xcb: moved mouse to 1291,  228; button state 0
> xcb: moved mouse to 1302,  226; button state 0

Any idea what causes this? Apart from the obvious 'xcb' and 'QGestureManager'?
And more important... How do I get rid of this?
