I'm running into this, but it adds also backlashes were they aren't needed, resulting in an invalid autostart entry.

1. Add an autostart entry
2. Add something like bash -c "if [ "$XDG_SESSION_TYPE" = "wayland" ];then sfwbar" into the "command" lineedit
3. Check the file, it will have
   Exec=bash -c \\"if [ \\"\\$XDG_SESSION_TYPE\\" = \\"wayland\\" ];then sfwbar\\"
4. Edit it, and backlashes will double.
