Hi,

getting a black screen sounds like you are starting Xwayland manually
in rootful mode, where all X11 apps will show up inside the one
Xwayland window.

Usually people use the Xwayland rootless mode instead, where Xwayland
is started automatically by the compositor, and the X11 windows
integrate seamlessly with other native Wayland windows. There is no one
window for all of Xwayland.

Do you intentionally use the rootful mode, or were you just not aware
of the rootless mode?

For more information on rootful vs. rootless, see

Thanks,
