I have never seen the specific problem reported, but I have some suggestions:
1) Are you using a retained or non-retain window as opposed to a buffered window? You want a buffered window.
2) Is the view layer backed? I don't know ifthat could cause the problem, but I is a path to investigate.
3) Have you turned on Quartz Debugging to see which areas of the window are being redrawn? If so, where the highlighted areas redrawn or not?
4) Are you recursively causing displays? That doesn't work, so don't do it. Have you tried [outlineView performSelector:@selector(display) withObject:nil afterDelay:0.0f] instead of calling display again as the side effect of a display message?

The docs say:
Invoked when the dragging operation is complete, signaling the receiver to perform any necessary clean-up.
My question is how does one clean up all highlight artifacts in an NSOutlineView such as these:

I have tried -display , -reloadItem and reloadData all to no avail.
Steve Jobs was stumped and suggested this list might be helpful.
Was he right?
