Public bug reported: I'm not sure when this is happened. I've noticed that for VS Code and GitKraken. Alt+Tab however allow you to switch to the "not running" application.
Sometimes I've noticed that just after installing upgrades but in this specific case no updates were installed. Propably this is related to the https://bugs.launchpad.net/ubuntu/+source/gnome-shell-extension-ubuntu-dock/+bug/1828176, but this one appeared not only for the snap applications (GitKracken is snap application, VS Code is apt application) See the screenshot. $ lsb_release -rd Description: Ubuntu 20.04.2 LTS Release: 20.04 $ apt-cache policy gnome-shell-extension-ubuntu-dock gnome-shell-extension-ubuntu-dock: Установлен: 68ubuntu1~20.04.1 Кандидат: 68ubuntu1~20.04.1 Таблица версий: *** 68ubuntu1~20.04.1 500 500 http://ru.archive.ubuntu.com/ubuntu focal-updates/main amd64 Packages 500 http://ru.archive.ubuntu.com/ubuntu focal-updates/main i386 Packages 100 /var/lib/dpkg/status 67ubuntu20.04.5 500 500 http://ru.archive.ubuntu.com/ubuntu focal/main amd64 Packages 500 http://ru.archive.ubuntu.com/ubuntu focal/main i386 Packages ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: gnome-shell-extension-ubuntu-dock 68ubuntu1~20.04.1 ProcVersionSignature: Ubuntu 5.4.0-79.88-generic 5.4.124 Uname: Linux 5.4.0-79-generic x86_64 ApportVersion: 2.20.11-0ubuntu27.18 Architecture: amd64 CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME Date: Thu Jul 15 09:32:04 2021 InstallationDate: Installed on 2020-11-24 (232 days ago) InstallationMedia: Ubuntu 18.04.3 LTS "Bionic Beaver" - Release amd64 (20190805) PackageArchitecture: all ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=ru_RU.UTF-8 SHELL=/bin/bash SourcePackage: gnome-shell-extension-ubuntu-dock UpgradeStatus: Upgraded to focal on 2020-11-25 (231 days ago) ** Affects: gnome-shell-extension-ubuntu-dock (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug focal third-party-packages ** Attachment added: "GitKraken disappeared.png" https://bugs.launchpad.net/bugs/1936283/+attachment/5511024/+files/GitKraken%20disappeared.png -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell-extension-ubuntu-dock in Ubuntu. https://bugs.launchpad.net/bugs/1936283 Title: Sometimes application is not shown as running in the dock To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell-extension-ubuntu-dock/+bug/1936283/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
