Comment (by smizuno):

 It appears that QLabel is doing a lot of work to paint the new values.
 Perhaps using a QLineEdit control would be better. The CoordinateCapture
 tool has two such controls, plus it does coordinate transforms, and its
 CPU utilization isn't any more (actually less in my testing on Windows)
 than the mouse cursor position control.
