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. However, other options in the xpra menu like Encodings, Quality and Speed are greyed out and cannot be changed. 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?
