When opening and then closing the dash quickly the panel is too slow to update

[Brandon Schaefer]

When you open then close the dash quickly the panel is too slow to keep up with the current state of the dash. Leaving the panel thinking the dash is open when it is closed.

To reproduce:
Double click on the Dash icon in the launcher...

I wasn't able to reproduce this here, on Quantal, unity trunk. It's probably because of the multimonitor setup on your system which probably slows down the opening/closing of the dash.

I don't have multimonitor setup. Plus my machine is quite fast I would say

I've seen a re-occurrence of this with:
 - compiz - 1:0.9.8.2+bzr3377-0ubuntu1~test2
 - nux - 3.6.0-0ubuntu1~test2
 - unity - 6.6.0-0ubuntu1~test1

unity was built by Timo, so I'm assuming it has this fixed based on the related branch:
lp:~timo-jyrinki/ubuntu/quantal/unity/ubuntu.660

[Omer Akram (om26er)]

yeah, the issue is still there. Its very clearly visible on low end machines.

[Launchpad Janitor (janitor)]
