Most of the launcher and top bar freeze occasionally

[Alexander Adam]

I think this happens mostly after locking and unlocking again.
Clicking on the trash bin works as well as the tray icons.

I switch the focussed application the title bar also changes but I am unable to reach the application menu.
Launching applications by clicking on the launcher icons doesn't work but the icons refresh themselves on state differences.

So I am able to see wether an application is started and the workspace indicator also refreshes.

I am running Ubuntu 14.04 with Unity 7.2.0+14.04.20140423-0ubuntu1.2 and this problem is available since I upgraded to 14.04.
This bugs me a lot (happens on a daily basis).

PS: it is currently frozen if that helps in the combination with the data from apport

Thank you for your bug report. Do you use a dual screen configuration? Could you describe exactly how to trigger the buggy state?

[Alexander Adam (7ql6)]

Yes it is a dual screen configuration (DELL UX2711 on an ASUS UX31A) but I have to admit that I have no reliable way to reproduce the problem for now.
Sometimes 'it just happens'.

Yesterday the problem was 'fixed' as I locked the screen and unlocked it again.

I have no idea wether this is relevant, but I have to execute some xrandr commands for using the correct resolution for the monitor (also described in another bug report: https://bugs.launchpad.net/ubuntu/+source/unity-settings-daemon/+bug/1310745 )

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