Does turning off »Use Graphics Processor« in the Performance Preferences and restarting Photoshop have any bearing on the issue?
So far so good. I will continue to monitor it.

Not so; if turning off »Use Graphics Processor« were to resolve the issue it could indicate that your GPU driver needs to be updated (or the reverse) and as long as it’s turned off you lose a bunch of functionality that dependes on it (the Rotate View Tool for example).
Turning off the graphics processor has actually not fixed the problem, ghost data shapes appeared again today.
What are your OS and hardware specs?
Are Photoshop and OS fully updated?
What have you done in way of the usual trouble-shooting routines (trashing prefs, system maintenance, …) so far?
I'm running OS X 10.6.8 on a Mac Pro quad core. 2.4 GHz processor speed. 32 GB of memory. I have a ATI Radeon HD 5770 and Nvidia Ge force 8800 GT video cards and an Eizo CG243W.
The issue I believe has been present for about a year, I'm running CS6 which has been re-installed a couple times and is up to date. I generally only run PS, Chrome, Outlook, and iTunes. Although will end up with AI and Acrobat and sometimes InDesign on occasionally.
My machine has also been fully wiped and the OS re-installed. We've also swapped out my data drives. There is also often a scrambled patchwork on re-draw, while opening files in PS, or zooming in. My instinct says its a video card monitor PS thing but the video cards have also been swapped out with no difference.
