Public bug reported: There is an issue on Ubuntu 20.04 / 20.04.1 where the ubuntu dock extension for gnome is misaligning the preview window - it should be centred based on what I've seen online. This was a fresh install of Ubuntu 20.04 close to or just after release.
People are discussing the issue on Stack Exchange here: https://askubuntu.com/q/1183065/10857 with the following answer fixing the issue for most people: https://askubuntu.com/a/1232740/10857. The problem with that fix is that people shouldn't have to do that - it should already be baked in, so I'm making it aware here so someone can apply this fix if possible since you'll know better if this will break other things or not. 1) $ lsb_release -rd Description: Ubuntu 20.04 LTS Release: 20.04 2) $ apt-cache policy gnome-shell-extension-ubuntu-dock gnome-shell-extension-ubuntu-dock: Installed: 68ubuntu1~20.04.1 Candidate: 68ubuntu1~20.04.1 Version table: *** 68ubuntu1~20.04.1 500 500 http://gb.archive.ubuntu.com/ubuntu focal-updates/main amd64 Packages 500 http://gb.archive.ubuntu.com/ubuntu focal-updates/main i386 Packages 100 /var/lib/dpkg/status 67ubuntu20.04.5 500 500 http://gb.archive.ubuntu.com/ubuntu focal/main amd64 Packages 500 http://gb.archive.ubuntu.com/ubuntu focal/main i386 Packages 3) Expended the window to be centred in the preview. 4) Preview is left-aligned and looks out of place.
