I'm having the same issue, I made a video to illustrate the problem. However gtk recordmydesktop was giving me a hard time recording both of my screens so there are some corruptions, most noticeable the fact that only the left upper side of the menus show. However it does show the problem.
On the left monitor the menus behave very unpredictable, sometimes they work, sometimes they don't. Mostly, after the click, the menu just pops up and immediately disappear again. However on the right monitor, the menus are pretty stable (sometimes they flicker when opened, but at least they stay open after that) ** Attachment added: "Video of the bug" https://bugs.launchpad.net/ubuntu/+source/unity/+bug/861375/+attachment/2556621/+files/out-1.ogv -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/861375 Title: Indicators don't stay open in multimonitor setup To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/861375/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
