I disabled the extensions you listed and could still reproduce it. Then I also started to disable the extensions shipped with Ubuntu, it also happens with 'Ubuntu Dock' disabled.
However, at least right now, I cannot reproduce it when 'Desktop Icons NG (DING)' is disabled, so maybe this is the problematic extension? -- 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/1928312 Title: ghost compose window with wayland Status in gnome-shell package in Ubuntu: Incomplete Bug description: After writing a new email and sending it, gnome still sees the compose window, even though it is really closed. * Ubuntu Dock has an additional dot next to the thunderbird logo * Clicking in the top bar on Thunderbird has the compose window listed under "Open windows" * Using get_windows() in looking glass on the thunderbird app object gets 2 objects of MetaWindowWayland Even after closing the main window of thunderbird, the ghost window is still there (dot next to thunderbird logo in ubuntu dock), which means Ubuntu Dock is not launching thunderbird on single left click any more. Right click on the thunderbird logo in this state just opens an action window which doesn't respond to any clicks. Only logging out and back in seems to restore normal behavior. This is happening since upgrading to Ubuntu 21.04 and using wayland by default. It doesn't happen 100% of the time, but often enough for me to be able to collect additional information if necessary.
