Okay, what I did was:
On the xpra server:
$ Xvfb :10 -screen 0 3840x2160x24+32 -fbdir /var/tmp &
$ export DISPLAY=:10
$ xterm && leafpad &
On the client:
$ XPRA_RANDR=0 xpra start --use-display :10
Only disabling OpenGL allowed to render opened windows.
AFAIK, Xvfb does not support OpenGL.
And if you use Xdummy, you often need to use VirtualGL:
http://xpra.org/trac/wiki/Usage/OpenGL
However, other
options in the xpra menu like Encodings, Quality and Speed are greyed
out and cannot be changed.
That's because they are meaningless in this case as you are probably
using mmap.
This can be seen in your server log file.
On the server:
$ ffmpeg -f x11grab -s 3840x2160 -i :10 -r 24 -deadline realtimeb:v 1M
-threads 5 -qmin 0 -qmax 50 -crf 5 -preset ultrafast -f matroska
4k_screencap_xpra.mpv
The screencapture shows everything black including changes made in
the xpra attached windows except cursors movements are captured.
Any hint why the capture is not displaying the contents of the windows
other than mouse movements?
Since you are not using "sync-xvfb", the xvfb will remain black.
This thread now almost has as many posts as the mailing list has had in
September and October combined.
Please slow down, read the manual, the wiki and the links provided.
Cheers

Thanks!

If you are certain that you will only need a single resolution, then

could also use a customized xorg.conf
The "desktop-scaling" option in 0.16 looks easier to me than either of
those options.
any man pages about desktop-scaling?
Can you please check before asking?
man xpra
And also here (the second link on the wiki):
http://xpra.org/manual.html
Sorry I skipped the part in the man-page. Still I could not figure out
the sync-xvfb part in the man pages.
After reading the --desktop-scaling part, the parameter allows to
control the server's x resolution on the fly.
But I am trying to do the other way round. The server's virtual X
remains at the 4K resolution while the client's varies according to
the physical screen attached.
Thanks again,
