sorry just saw more questions, answering!

$ gnome-extensions list --enabled
ubuntu-d...@ubuntu.com


hmm after executing this - 
gnome-extensions disable ubuntu-d...@ubuntu.com


my Ubuntu left panel with icons is GONE! :)

that's very unfortunate :)


2) only one process is eating > 90% of CPU (seen in htop) - is gnome-shell
