Clicking on an app icon doesn't work if it's opened in another workspace

[Tiger]

My Ubuntu version is a 16.04 LTS.
I make regularly updates using the console commands.
sudo apt-get update upgrade dist-upgrade autoremove

Steps to reproduce the bug

1- open an app, for example the terminal in workspace 1

2- go to workspace 2 and click in the left bar on the terminal icon

Results: the process is not switching to workspace 1 where the terminal is already opened.

It was working perfectly before and I made no changes to my system except the updates.

I discover this issue with another one.

Some applications, it's the case for terminal, when being opened are placed too high and their handle title bar are behind Ubuntu top bar.

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers.

I have classified this bug as being an issue in the 'unity' package as that is the default desktop environment in Ubuntu 16.04. If you are not using Unity then you will need to reassign this bug report to the package which is related to the desktop environment that you are currently using.

Please execute the following command as it will automatically gather debugging information, in a terminal:

   apport-collect 1883390

When reporting bugs in the future please use apport by using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.

About compiz which is listed in apport-collect information.
This is something I found while trying to find information about the bug.
Someone was speaking about it, I installed it with:

sudo apt-get install compizconfig-settings-manager

But I never used it.

I've some news about this bug.

I've another PC with Ubuntu 16.04 installed. The updates had not been made since some time.
I checked that the bug was not existing at that moment.

Then I did the system upgrade with sudo apt-get update, upgrade and dist-upgrade, autoremove.

And the bug did not occurred...

I know that if the developers are not able to reproduce, they'll not be able to fix that bug for my laptop.

I'm going to try to find the differences between the two laptops to give you information, but I know that maybe I'll never find it.

The most annoying is the fact that the handle of title bars of some windows are behind the Ubuntu top bar, but I can manage it with alt + mouse right click to move windows.

Maybe some Ubuntu devs will have the bug.
