Unity is slow on Ivy Bridge

[Tommy_CZ]

Hi, I am trying 14.04 and as I see Unity DASH is slower than in 12.04.3, opening is being did in 4 steps each really visible. When DASH is opened maximised it is even more visible. It takes about 2 seconds and I think this is not fast enough.

And when I try to close DASH it do not react sometimes, so I click 3times more and it do a carousel - opening and closing.

Also hovering on lenses is painfully slow.

One of the last updates before the final version of 14.04 fixed it for me.
