With your last change this issue was fixed:

Always repaint the gray area below main inset
   
Now that SingleParUpdate does not always lead to a full screen        
update when the height of the paragraph changes (see new behavior 
of updateMatrics(bool)), it is necessary to make sure that the        
grey area below the main page is always repainted.
