1password often ends up with multiple instances running (each with its own trayicon)

Hi carpii, thanks for the additional information here. We'll be happy to look into this further.

A quick question: what command-line shell are you using on this device? Bash, zsh, something else?

Given that further discussion of this issue likely involves discussing the specifics of your system, I'll invite you to follow up with a brief email to us at support+linux@1Password.com. That way our team can dig into the details and figure out the cause of this for you. 👍

Thanks again for letting us know about this, and we'll look forward to setting it right!
