But I also note this other problem which is not reproducible each time but I guess this bug is related to this one:
* Open two maximised windows: one on the first workspace, the other on the second one.
* Switch between workspaces and the focus will not changed.
e.g. I have my text editor on workspace 1 and Firefox on the next workspace. My text editor's window has the focus and it keeps it even if I switch to the next workspace.
I also have this kind of problem.

I didn't have this bug on Ubuntu 14.10.
