I'm having this same issue. I have disabled the autostart using settings, but the app still starts at boot.
> Do you right click on tray icon of Enpass or Enpass just appears on screen after startup without doing anything?
My answer to this question is, it pops up, not minimized.
This is the log entry when it starts:
~ % sudo journalctl -b | grep -i 'enpass'
Oct 23 22:32:52 m systemd[616]: Started Enpass - Enpass Password Manager.
Here is some systemd output:
~ % systemctl --user list-units | grep -i enpass
