GNOME Bugzilla – Bug 704502
Workflow-crushing lag when searching for applications
Last modified: 2014-04-26 15:22:10 UTC
Created attachment 249570 [details] The screen where the lag happens. I am experiencing a 4-to-6 second lag (rough estimation) when trying to search for applications in the overview. This is the detailed scenario: 1. I'm working in some window, and decide that I need to search for an application and open it. 2. I press the Super (Win) key, and the overview is shown (no lag here). 3. I start typing - LAG When I type the first letter, the initial set of applications appear on the screen virtually instantly. However, gnome-shell starts lagging then, no matter what I do. Trying to quit the overview dos not help, everything is simply stalled for a few seconds. Also, most animations, in the overview, the regular view, and windows, work just fine, so I doubt this could be GPU driver-related issue. I am experiencing this on a completely new Fedora install, and the only modifications I have made to gnome-shell is some configuration with the GNOME Tweak Tool. I have no extensions installed. I have the HP ProBook 4530s laptop.

I honestly hope this is fixed soon as I really like GNOME. -- I would've filed this as a MAJOR bug personally, but since this is my first time reporting a bug with this system, I left it at default. If possible, please change its severity to MAJOR, as this really is a major bug (although it doesn't cause crashes, which might be a criteria for a MAJOR bug).
I've found the equivalent bug report on the Fedora downstream: https://bugzilla.redhat.com/show_bug.cgi?id=964764. The bug report suggests that the lag only happens when the user is logged into an online account and his status is set to "Online". As confirmed by my attached screenshot, my status was set to "Online", and I was logged into Google and Facebook. I have still not confirmed whether setting the status to something other than "Online" actually removes the lag.

The issue now seems largely fixed. I logged into Google and Facebook, set the status to 'Available', and I could experience no lag with searching. Has it actually been fixed, or is this just an anomaly?
Closing as of comment #3.
