Hi Aren,
We updated recently to the last NGUI update (we were 5 or 6 update behind).
Since this day, scene view is almost unusable because when we move some objects around, CPU increase to 100% during all the move.
We did a profile of the editor and linked the result to this topic.
At first we thought it was because you call Profiler.BeginSample in an ExecuteInEditMode script but after removing it we have the same problem.
We are on Unity 5.3.6p2 and this bug is very annoying because we can't place our widgets properly like before.
Do you have the same problem on your side?
