Sorry to dredge up an old thread, but I noticed the Ghost View was less-than-great in today's modeling session.
Normally, I do ALL of my modeling with the computer in BootCamped Windows 7 running Rhino 5. There, everything works well.
This past week, I thought I'd hang around on the OSX side and model in Rhino for Mac.
In my usual Rhino sessions, I'll occasionally toggle the screen to Ghosted mode to better understand a complex shape. This is when I realized I wasn't getting the Ghosted mode I normally see in Windows Rhino -- keeping in mind both programs are using the same underlying hardware (i7 Retina MacBook Pro). I haven't mucked around in Rhino OSX's graphics settings, so presumably it's all at their defaults.
Apparently objects (polygons) that have flat faceted surfaces do appear ghosted as expected, but complex surfaces do not:
