Hi! Sorry for the late answer. Here is the return for `vlc --version`. The issue is relatively difficult to reproduce: I have a set of mkv/webm files that do it all the times, but if I set-up VLC with other files (mp3), the issue does not appear.
```bash $ vlc --version VLC media player 3.0.8 Vetinari (revision 3.0.8-0-gf350b6b5a7) VLC version 3.0.8 Vetinari (3.0.8-0-gf350b6b5a7) Compiled by buildd on lcy01-amd64-014.buildd (Sep 11 2019 11:39:37) Compiler: gcc version 7.4.0 (Ubuntu 7.4.0-1ubuntu1~18.04.1) This program comes with NO WARRANTY, to the extent permitted by law.

Once LibreOffice was ready, it appeared “by surprise” in the Alt+Tab menu of another workspace. VLC and LibreOffice are both large softwares: maybe they both launch some kind of global instance in addition to the windows, and it is this global instance that trigger the Alt-Tab notification? I can’t tell, apart from the fact that each time this happens, I’m being caught by surprise 😅 I attaching the logs. At the time 11:50, it was VLC doing the Alt+Tab appearance in another workspace, and at 11:54, it was LibreOffice. I will try to reproduce the issue in a newly created session. ☺ Have a nice day ☺ Martin. ** Attachment added: "result of ` journalctl -b 0`" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1865337/+attachment/5364333/+files/log3 -- 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/1865337 Title: Gnome 3 keeps adding VLC in Alt+Tab Status in gnome-shell package in Ubuntu: New Bug description: 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.
