Thanks for your explanation of how gnome-shell workspaces work or should work.
I'm not seeing this problem with Ubuntu 18.04 where all applications remain visible on the workspace that they are on before gnome-shell is restarted. I don't use Ubuntu 18.10 due to gnome-shell crashing when restarted: bug 1796607. I don't think this is a duplicate of bug 1181666 as it is only the windows that gnome-shell has failed to hide that are not clickable. The 'wanted' application, the dock and top bar all function correctly. I'll update the bug description a little. ** Summary changed: - Restarting gnome-shell produces images of applications running on other workspaces + Restarting gnome-shell displays images of applications running on other workspaces ** Description changed: - Restarting gnome-shell with 'Alt-F2,r and enter' produces images of + Restarting gnome-shell with 'Alt-F2,r and enter' displays images of applications running on other workspaces which are not clickable.
