1. For those black spots, if you are still experiencing them: Check out this Clash of Clans for PC page. Scroll down to "some common bluestacks problems" and then scroll down to "black buildings and objects."

2. For getting the game to close check out this page. The topic is "closing apps on bluestacks using advanced task killer."

3. Get an android device. :P

Hope this will help.
