[panel] navigation between application menus temporarily gives focus back to the application

Hi Omer

Description: Ubuntu 10.10
Release: 10.10
unity-2d-default-settings:
  Installed: 0.4-0ubuntu1~bzr405
  Candidate: 0.4-0ubuntu1~bzr405
  Version table:
 *** 0.4-0ubuntu1~bzr405 0
        500 http://ppa.launchpad.net/unity-2d-team/unity-2d-daily/ubuntu/ maverick/main i386 Packages
        100 /var/lib/dpkg/status

I can confirm that when using the package unity-2d on ubuntu 10.10 using the steps provided by Omer Akram that I can reproduce the bug. Therefore I have set this bug to confirmed.

Also I can confirm the behaviour that this problem doesn't exist when navigating system indicators.

I cannot observe that issue Omer. Maybe I am not looking at the right thing. Do you have any tips?

Also, are you using metacity?

at the moment indicators are broken in unity-2d so cant test it. as soon as
they are back i'll report

Hi Florian

I am running Ubuntu 10.10 and I have installed unity-2d from the ppa. I have not manually installed metacity but it seems to have installed one from the ppa itself (see below). Also I am experiencing the same issue as Omer (I confirmed the bug).

metacity:
  Installed: 1:2.30.2-0ubuntu1upicek6
  Candidate: 1:2.30.2-0ubuntu1upicek6
  Version table:
 *** 1:2.30.2-0ubuntu1upicek6 0
        500 http://ppa.launchpad.net/unity-2d-team/unity-2d-daily/ubuntu/ maverick/main i386 Packages
        100 /var/lib/dpkg/status
     1:2.30.2-0ubuntu1 0

If you want any more information just ask.

Hope that helps.

Bumping importance as it could cause performance issues on low end machines (BAMF reacts to focus changes, D-Bus traffic happens and the launcher reacts as well).

The implementation of QMenuBar in Qt4.7 does not hold onto focus while panning horizontally through menus with the mouse or keyboard. In the brief pause between one menu closing and another opening, the focus is returned to the application, causing the flicker.

This behaviour can be seen in other native Qt apps like Qt Creator or KDE apps like Kate. However it is more noticeable in thus dbus-based menus, due to the fact that each menu display causes dbus traffic which elongates the pause between menus.

GTK menus do not have this focus problem, hence the indicator bar does not exhibit this issue.

Have reported to upstream Qt: https://bugreports.qt.nokia.com/browse/QTBUG-20532
Will lower priority for now.

This bug was fixed in the package unity-2d - 3.8.12-0ubuntu1
