Comment 76 for bug 1721428

I reproduce the same thing with a pretty standard Ubuntu 17.10 (but upgraded from 17.04) in which I did not installed any extension (which mean I only have the system Ubuntu ones: "Ubuntu AppIndicators" and "Ubuntu Dock"). I wanted to try to disable those extension to check but it does not seems to be possible (at least not from https://extensions.gnome.org/local/).

My system is a Nuc Arches Canyon Nuc6cayh.
