It does.
But that's not going to help with shadow mode, which only exports one
window. (the whole screen is one window in shadow mode)

* jpeg at 40% quality will look awful

I assume that this ":2020" display is running an xpra seamless session?

Don't use a second server in shadow mode for this.

You can record the vfb with ffmpeg as long as you set the --sync-xvfb
option when you start your session.
