Gnome 3 keeps adding VLC in Alt+Tab

Hi,

I have these two settings on: https://askubuntu.com/questions/464946/force-alt-tab-to-switch-only-on-current-workspace-in-gnome-shell and https://superuser.com/questions/394376/how-to-prevent-gnome-shells-alttab-from-grouping-windows-from-similar-apps
I would thus expect that Alt+Tab would only show apps from the current workspace. However, I have VLC on another workspace, and Gnome 3 always show VLC as first app in Alt+Tab. To remove the app, I have to go to VLC’s workspace, and focus its window. But then when VLC will switch song, it will go again as first app in Gnome 3’s Alt+Tab shortcut in ALL workspace.

This is my number 1 issue in Gnome 3 that just makes me crazy: as VLC is shown as first app when I do Alt+Tab and that the current app is thus shwn second, doing Alt+tab quickly leaves the current app as current. Because VLC was shown first and the current app second, Alt+Tab goes to the second element, that is, the current one. This basically makes Alt+Tab completely useless for me, and I have to press the super key each time to switch windows. This is extremely annoying.

Of course, I could just type Alt+tab+tab to switch to the third app, expect that (1) this is extremely counter-intuitive, and (2) depending on whether VLC is adding this “all workspace Alt+Tab notification” or not, the semantics is not the same.

Note that I have prevented VLC to display any notification. This prevents VLC from adding overlay notification, but does not prevent VLC to do this Alt+Tab notification.

This is incredibly annoying. As the semantics of “/org/gnome/shell/app-switcher/current-workspace-only” is *not* to only switch between current workspace (as it always adds VLC’s notificationsm whichever workspace VLC is), I suggest to either rename it or fix its behaviour to match its name.

Attachment: a screenshot of my screen when I do the Alt+Tab. As the print-screen button in Gnome 3 frustratingly does not work when pressing Alt+Tab, I took it with my phone. In this case, I have Firefox opened as well as a console in this workspace, and VLC is in another workspace. I have a lot of other apps in other workspaces too, but they do not trigger this “Alt+Tab notification”.

Regards,
Martin.
