Steps to reproduce:

1. Set TemplePlus.ini to:
   windowHeight=600
   windowWidth=1024
   windowed=true
2. Run T+ in Windowed mode and then maximize window;
   Issue: PC and NPC which are in area of the screen which resembles not maximized window will show hint when hovered. But ones, which are to the right or left from that area will not.
