** Attachment added: "prevboot.txt" https://bugs.launchpad.net/ubuntu/+source/gnome-shell-extension-ubuntu-dock/+bug/1922353/+attachment/5498566/+files/prevboot.txt -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell-extension-ubuntu-dock in Ubuntu. https://bugs.launchpad.net/bugs/1922353 Title: Overview sometimes fails to appear or disappear in 21.04 Status in gnome-shell package in Ubuntu: Incomplete Status in gnome-shell-extension-ubuntu-dock package in Ubuntu: Incomplete Status in gnome-shell source package in Hirsute: New Status in gnome-shell-extension-ubuntu-dock source package in Hirsute: New Bug description: When I press the "windows" or "options" or "super" key a list of running applications (like alt-tab) and a text window appears. I can choose from the running applications or write a command into the text window. After I chose an application or press ESC all this disappear and I can do my thing. Since trying 21.04 sometimes this 1. does not appear properly - there is no visible text window 2. does not disappear - despite what I click on or what keys do I press this never disappear so I can not use my running applications or start anything new even from the menu. I have to log out and in to break this. Disabling my gnome-shell extensions or using xorg instead of wayland does not helps. Since upgrading this morning this happens every time I press Super, not just occasionally, thus making my desktop unusable.
