Every once in awhile my screen will go crazy and almost pixelate.  It only happens in Chief and I have to completely close down my computer to reset to keep working.  I'm on a Mac. Spec for my computer and a screenshot are included. 

Every once in awhile when I'm working in the camera mode the screen gets "digitized" for lack of a better word.  I'm running Chief on Mac and connected to a second screen.  I think this also will happen when not connected to a second screen. It happens on the second screen I have at home as well. What is happening? 

I am trying to have tile continue along a backsplash that also includes a door frame.  In the door frame area the tile pattern doesn't show up.  How do I make that tile appear. Screenshots attached showing the area that the tile should be in and the appearance of the tile.  That area is a doorway.

In Chief Architect x15 the bounding box for the toilet is not there anymore.  I've looked up how to put it back, but the steps are outdated
