Lock screen can lose focus and send keystrokes to some other application

[Mike Gerow]

I have a user that reported the unity lock screen losing focus and sending keystrokes to the application behind it. This seems similar to https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1358504 but that bug is marked as fixed.

In their specific case they were using chrome with google hangouts (using chrome's google hangouts extension: <https://chrome.google.com/webstore/detail/hangouts/nckgahadagoaajjgafhacjanaoiihapd?hl=en>) when they locked their screen. Upon coming back they typed their password and hit enter, but the screen did not unlock. They had to manually click in the password field and type their password before it would unlock. Upon unlocking they discovered that they had a hangouts window open with a colleague and had sent their password to them (I'm assuming during that first try when the lock screen did not unlock).

$ apt-cache policy unity

  Installed: 7.2.3+14.04.20140826-0ubuntu1.0.1

I'm currently trying to find a way to reproduce this, but haven't managed to yet.

Mike, the number of reports of this kind of behaviour have dropped dramatically since this update was released; my first thought is that perhaps the computer hasn't been rebooted since 7.2.3+14.04.20140826-0ubuntu1.0.1 was installed, and an older version was still running.

Do you know if the session had been restarted since the package was installed?

Thanks

The machine was rebooted a little over a day ago. I'm pretty certain it had the update well before then.

Status changed to 'Confirmed' because the bug affects multiple users.

Can you still reproduce this problem?
