I've attempted to use gnome-network-displays a few times, creating a
virtual display and sharing that display on a Chromecast on the local
network. When doing so, the entire GNOME desktop crashes, dropping me
into GDM to log back in.

I am uploading gnome-network-displays 0.92.1-1 now so try the new
version. Both this version and the version you tried worked for me
using the Chromecast protocol. Could you try to provide a bit more
information?

What version of GNOME Shell are you using?

Are you using X or Wayland?

Is there anything unusual about your system you should mention?

If you are using Shell extensions, have you tried without them?

Does it still crash if you try while logged in as a new user?

Try looking through your systemd log with journatlctl to see if there
are related errors.

Thank you,
Jeremy Bícha

Hi Josh,

I uploaded network-displays 0.92.1 yesterday. Can you try this version
and see if you still run into this issue ?

Wayland.

Nothing that I can think of. Tested with latest sid as of today.

No, I'm not running any extensions.

Yes.
information.

Attempting to cast a window, or the whole screen, appears to work now,
but with 8-10 seconds of lag, making it unusable. (I'll report that as a
separate bug.)

Attempting to cast a virtual monitor still causes a crash. Here are logs
from that attempt:
