@paultait22 I agree that the problems are almost certainly related, but for bug fixing it is important to clarify what version resulted in what variation of the bug so that devs can look at the changes between versions and figure out where things went from bad to worse. Most developers don't have time to read the comments and aggregate all the knowledge they contain. Typically they read the initial bug report, briefly scan the comments for clues, then declare the bug fixed as long as the initial problem is solved. Since your problem has one additional condition, it is worth making a separate bug report that ALSO mentions this bug report.
Hopefully in the future launchpad will offer an option for adding bug variations so that a single report can house all the very similar but non-identical bugs under one roof. -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

It can take 3-8 seconds to change *tab*. During this time the CPU is maxed out; typical output from 'top' during this period shows 'hud- service' and 'unity-panel-service' combined using about the same CPU as Firefox itself: 100 10.4 26:07.73 firefox 53 0.6 6:14.86 hud-service 38 1.5 6:42.14 unity-panel-service I suspect that the change is causing a (an inefficient) re-index related to updated menu structures. (Eg. something like the history menu, although I can't see what it is as don't currently have a menu bar).
