Something very strange has started to happen. I have not changed the configuration of my Star Trek Online install, but it now starts a second instance every time I launch it. Clicking the first time, I get the launcher with the password prompt and enter the password. But shortly after I click login it launches a second copy with the password already entered, because the second one is also logged in and ready to go.
This is the current Lutris running on Devuan 3.1 (Debian with systemd extracted) and I installed using the Debian install method given on the download page here.
