I have this same issue with a freshly compiled version of KiCad (2014-04-25 BZR 4828) on Mac OS X (10.9.2). Makes it unusable.

This issue persists for me as well, when compiled on my 10.9.x system. The following patch to the overlay.mm linked in the referenced instructions fixes the issue for me.

I think I have the same issue in KiCAD 5.0.2_1. When I scroll across the sheet while dragging or cloning a symbol, it creates several mirages of it on my screen. I can clear the mirage by zooming in then out.
I am on Windows 10.
