Menu apps disappear!! Argh! Only come back when I reinstall indicator-appmenu and reboot the system!

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, we cannot work on this bug because your description didn't include enough information. You may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem.

We have instructions on debugging some types of problems at http://wiki.ubuntu.com/DebuggingProcedures.

At a minimum, we need:
1. The specific steps or actions you took that caused you to encounter the problem.
2. The behavior you expected.
3. The behavior you actually encountered (in as much detail as possible).
Thanks!

Hi, I'm use the Ubuntu 16.04 LTS, on notebook Sony, x64, Intel, Nvidia 310M, model VPCCW23FX.

The menus were functioning normally before the upgrade, however they began to fade, sometimes appear when it is done the system reboot and other times it is necessary to reinstall the "indicator-appmenu".
The menus that disappear are the native applications of Ubuntu, such as gnome-terminal, nautilus, gnome-calculator, rhythmbox, among others. In Firefox they continue to work.
I use the LIM option (Locally Integrated Menus) and think very efficient and very important.

So, I hope to have sent enough information, if necessary details, just ask.
