For my Gnome Shell, I have disabled that Workspaces should be on primary display only. So now, whenever I switch the workspace, both monitors switch their content as they should.
Yet when I press Meta in order to get a preview of my Workspaces, all I see is the preview of the workspace's content of the primary monitor.
This makes navigating my worksapces pretty hard as I have to know on which secondary monitor some window is hiding.
How do I get a prewiew of all monitors' content in the preview?
