Keyboard based app launcher falls behind

[Michael Hope]

If I hit Super, type in the prefix of the application I want to launch, then hit 'enter' then sometimes the applicaiton is not started.

It seems the search results aren't populated quick enough so the lens hasn't yet shown the search results and has nothing to launch.

I have a recent enough laptop with the fglrx driver. I suspect the rendering is taking too long and holding up the results.

As a self-described power user I find this annoying as I have to pause on common operations.

I don't have this issue with the latest version of Unity in Precise. Tried multiple times by typing something very quickly and then pressing enter, but it always launched what I wanted.

This is very repeatable on my machine. unity is 5.4.0-0ubuntu2. I last updated end of last week.

for me the dash search is indeed really quick, it used to be slow in Oneiric. I believe your specific bug could be possibly related to some fglrx issue.

[Michael Hope (michaelh1)]

The problem is exposed by the driver, but I think you have a race condition in your code. The dash should wait for the search to finish before launching the application instead of running the first thing shown when enter is pressed.

this is something that we need to track its been happening for quite a few people. I confirm the issue as well.
Note: it does not happen all the time
