Our Bluberry iMacs will display a white stripe from the bottom of the screen when the mouse touches the bottom edge of the display. I Googled, and it appears to be a unique problem.

Are you running OS X? If so, I have a strange feeling your problem is Dock-related.
No, it's not OS X. I think its hardware related, as it does not show up in screenshots.
