GStreamer and Linux, screen recording works well on Xorg but not on Wayland.

Hi all,
I'm trying to use GStreamer on Wayland and it seems to have some problems...

This pipeline:
gst-launch-1.0 ximagesrc startx=1 endx=3839 starty=0 endy=2159 ! 
video/x-raw,framerate=30/1 ! videoscale method=0 ! ximagesink

works well on Xorg, but not on Wayland.

On wayland I have this error:
Setting pipeline to PAUSED ... Pipeline is live and does not need 
PREROLL ... Pipeline is PREROLLED ... Setting pipeline to PLAYING ...
