My first thought is that gnome-shell might be blocked waiting to write log messages to disk, and indeed I do see a number of these in your log:
https://bugs.launchpad.net/ubuntu/+bugs?field.tag=logspam Can you open two Terminal windows and run 'top' in one, and 'journalctl -f /usr/bin/gnome-shell' in the other? Then repeat the bug and see if anything is hogging the CPU or flooding the log while it's happening. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/2000743 Title: kinetic: UI unresponsive while lengthy disk operations complete.
