I believe https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1060580 is related to this bug, since that bug report describes lag during the panel fade event. I've noticed it in 13.10 and 14.04, that there's a skip in an icon's position during dragging while the Unity panel initiates its fade animation. I'm almost tempted to link these bugs as duplicates, as I believe they're very closely related. At the time an icon skips in its path, in the same moment a drop event would be lost.. actually I will link them, pretty confident and I think it'd be fairly trivial for one of the Compiz/Unity guys to fix, seeing as it happens at such a specific time, and is very easily reproduced.
Drew Snellgrove's video in comment #17 is an extremely good demonstration (thanks Drew!)
