It seems this one is reporting the issue: https://bugzilla.gnome.org/show_bug.cgi?id=652580
There are few patches, but it does not like fixed. So I do not care so much about switcher than the behavior described: Observed behavior: Actvities overview (got by pressing the logo key), however, handles the two monitors differently: for the primary monitor, it exposes only windows on the current workspace, but for the external monitor, it always shows all windows on all workspaces. Expected behavior: when /desktop/gnome/shell/windows/workspaces_only_on_primary is false, both monitors should behave the same, and both should show only windows on the current workspace. ** Bug watch added: GNOME Bug Tracker #652580 https://bugzilla.gnome.org/show_bug.cgi?id=652580 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1743736 Title: In overview, windows from all workspaces are shown for the second display Status in gnome-shell package in Ubuntu: Incomplete Bug description: I have disabled workspaces on primary display only, and I have enabled workspaces to span displays, in tweak tool. Now things mostly work how I expect. Windows are isolated to the workspace they are and I can move them between displays (monitors). The issue is if I go into an overview mode. Then, for the primary display, I see only windows from my current workspace. But for the secondary display, I see windows from all workspaces being shown in the overview mode. I would expect that only the windows from the current workspace are shown also on the secondary display in the overview mode.
