I can reproduce it 90% of the times using the attached html file in both Chrome and Firefox (just one pre tag with enough text to show the horizontal scrollbar). In my case, scrolling it to the right and all the way back to the left, so that the mouse pointer is in the panel's area, cause unity panel to fail to reveal.
As I also found out, it doesn't have to be a web browser - text editor like GEdit will result in the same behavior, when a line is long enough to reveal the horizontal scrollbar. ** Attachment added: "Horizontal scrolling causes unity panel to fail to reveal." https://bugs.launchpad.net/ubuntu/+source/unity/+bug/970038/+attachment/4222332/+files/unity_panel_not_revealing.html -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/970038 Title: Launcher do not want to appear To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/970038/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
