Yes, it is that problem. Only I do not understand why all the discussion 
was reduced to discussing the shortcomings of QSettings?! Instead of 
figuring out why the save function is called so often. In fact, the save 
function is called for each mouse movement. I analyzed your code and 
wrote a small patch that solves this problem. The patch is attached.
