Comment 23 for bug 1932328

Yes, as I wrote in the duplicate bug #1938832 : after leaving a second red dot as if compose window was still opened, if I click on the Thunderbird icon on Ubuntu dock, it freezes the entire desktop, and I have to manually force shutdown.

I reported it upstream, but Dash to Dock development seems stopped - there is a fork on progress to adapt it to Gnome 40, but other bugs are not solved for the moment…
