It looks like I had some gnome shell extensions that were causing problems. I was able to get things to work by following the instructions here to disabling them: https://askubuntu.com/questions/591757/how-to-activate-deactivate-a -gnome-shell-extension-from-command-line.

Everything looked okey, however if I enter gnome shell "overview mode" I cannot leave it anymore, I can't select any window, type to search etc, and all my windows are in the foreground, covering the search bar etc, but not possible to select them. Simply I can't do anything. I can launch applications from the dock but cannot see and access them anymore. So basically I stuck in overview mode which does not work too much. What I can do, is to use the top panel to log out. If I do that, and login again, I only get a black screen and nothing more. I have to press the power button at that point to shut the computer off, so I can turn on again. It seems everything works, just entering into that "overview mode" kills everything then and only reboot helps from that point. Sorry, I am not sure what the official name of the gnome3 shell "overview mode" possibly I used the wrong terminology. Also, my bad English cannot help either to express the problem well enough, I guess.
