When exiting a room where one was host, server sends a REMOVE_TEAM for the local team. It appears that this loop would not break in that case. Add a log message and a break. (I've hit a frozen frontend twice now)
#include <QLabel>
#include <QRect>
#include <QList>

Q_OBJECT
public:
PixLabel();
QList<QRect> rects;
public slots:

private:
