Laggy and slow menus, often blocking the UI

[Jono Bacon]

With LibreOffice in Saucy I often click on a menu and see the menu background appear but no text in it. This will often lock up LibreOffice and Unity for around 10 seconds until the menu is drawn and then it seems cached and works fine.

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

The same in Sublime and in system tray icons

Building on Pavel Vorobiov's comment, I'd like to add that this happens with any menu on the Unity panel on my system.
I propose we keep this bug report as a separate entity from the LibreOffice bug and changing its target package.

I have the same problem. Sublime is really slow.

This solved my problems with Sublime.
