** Description changed: - Fresh installation of Ubuntustudio (Plasma desktop) with thunderbird - 91.1.2 (deb version, not a snap). + Fresh installation of Ubuntustudio 21.10 (Plasma desktop) with + thunderbird 91.1.2 (deb version, not a snap). When I use the restore or maximize button of the thunderbird window, the screen is not updated correctly, it takes a few seconds and maybe never finishes. However, when I open the application menu, the screen will be instantly refreshed and the thunderbird window is drawn correctly then. I was able to take some screenshots: https://i.imgur.com/uNGDG05.jpg shows the screen about one and a half second after hitting the restore button https://i.imgur.com/pvpv4Ir.png shows the screen about one and a half second after hitting the maximize button. Since I'm having this problem with thunderbird only, I don't think it's related to Plasma but the application itself, but who knows.
