Obviously it’s not a ghost but Mailspring keeps opening a popup window with a new outgoing email that contains an attachment named database-agent.js.
This seems extremely nefarious except that there is no recipient in the To: field.
The bigger problem is that it is annoying having to not only close these randomly generated windows, but I also have to then delete the drafts as they all end up in the drafts folder.
The worst instance was when I tried to search for a string of text in one of my accounts. A new window popped up with each character I typed in the search box. 16 new emails filling my screen suddenly.
I’m running the most current flatpak version 1.9.2 on MX Linux XFCE.
