I am using Ubuntu Tweaks to set a bottom of screen taskbar. Nautilus (Files) was pinned to the taskbar. I discovered that Waland was incompatible with my graphics card, so switched to Xorg. I think at this point the Files icon disappeared (and just possibly some others I have not noticed). I can launch Nautilus from the launcher, but the icon does not appear. Nautilus version 1:40.2-1ubuntu1 Expected behaviour 1: The pinned icon would remain visible on the taskbar. Observed behaviour 1: The pinned icon disappeared from the taskbar. Expected behaviour 2: When Nautilus is open the icon will be visible on the taskbar. Observed behaviour 2: When Nautilus is open the icon is not visible on the taskbar.
