Pieces of drawing disappear when panning

Hello,

I am running DS V1R3 on a Macbook Pro Retina 15", I7 processor, 2.6GHz 16GB.

I am trying DS on a large DWG file (more than 10 MB) relative to a residential building. 

When I use the panning tool, some areas of the drawing go out of screen (obviously): when I put them again inside the screen, some parts are missing.  The more I do it, the more parts disappear. If I zoom in and out everything goes back to normal. The problem happens even if the panning is slow. This is quite annoying. Is it a problem only for the Retina displays?

Thanks,

 

Francesco
