      Description

      Under a Wayland environment, apps that block UI updates whilst performing a long operation are likely to be disconnected by the Wayland compositor. In the case of Picard, the UI crashes (although any on-going file operations continue in the background).

       

      From #sway:

      <johanhelsing> milkii: That bug is more of a core wayland issue than a qtwayland one
      <johanhelsing> if we work around it in qtwayland, then the same hack would be needed for all other toolkits (and I don't think they do)
      <johanhelsing> the answer I got over in the wayland irc is basically: applications shouldn't be blocking the gui thread for that long, they should do the heavy tasks on separate threads
