I did, of course, know about the Xerox Star. But I was under the mistaken impression that it could not overlap windows.
Instead, I beleive the limitation was that windows could only be re-drawn in full, even if overlapped.
Whereas on the Lisa/Mac, overlapped windows could be redrawn, thanks to regions.
Fascinating blog with photos from early Lisa interface development:
