I can confirm the very same error. It started about 10 days ago. My machine is a Dell XPS15 laptop, 16gb RAM, Win8, etc. PI version is 1.08.03.1123. This started before I downloaded the latest.
To reproduce the error try to select a bunch of image or process icons. Then selected align left, for example. Drag those icons off to the right hand side of the screen. Somewhere during this the icons will be duplicated and start to behavior erratically. Even now, of the my image icons is"persistent" and showing up on this screen as I type this message.
The second attachment shows a bunch of iconized images on the right center of the screen. Prior to the error message that same group of icons was mirror imaged or "ghosted" on the other side of the screen. Once the icons are dropped, the error message appears.
