Launcher re-ordering became laggy

Can't reproduce here, can you reproduce it every time? Even after reboots?

I confirm on devel-proposed/krillin 121. It's so laggy that sometimes you end up in situation where icons are outside of the launcher (like omer) or overlap (cf screenshot)

This bug was fixed in the package unity8 - 8.02+15.04.20150318-0ubuntu1
