Won't stream on a locked workstation

Nobody has claimed this yet.

I don't know if I'm missing a setting but if i lock my windows workstation (so the only thing on screen is the login screen), OpenStream doesn't stream to my vita. It flashes on my vita and goes back to the connect/disconnect screen.

This is the log for Openstream if that helps:

Setup -
vita1000 running vita-moonlight (HD 0.9.2 versions)
pc running 5800x-Vega64 using latest OpenStream.
CPU h265 encoding (Ultrafast-high-2-8-20-1-23-30)
3 monitor setup with primary as 1440p. During streaming i have to disconnect side monitors so the main monitor is 720p alone for it to work.

No source file, test, or entry point is named. Start by reproducing the locked-workstation failure with the reported three-monitor setup and inspect the logged display-topology and DuplicateOutput errors; done means streaming remains connected while the workstation is locked.
