xwayland: Crash with SIGABRT (fatal error: Couldn't add screen)
Using Debian sid/unstable with gnome-shell 41.2-1, and xwayland 2:21.1.4-1, coredumpctl shows that XWayland terminated with signal SIGABRT. Unfortunately, I do not know, what the user did in that moment.
Core was generated by `/usr/bin/Xwayland :0 -rootless -noreset -accessx -core -auth /run/user/1002/.mu'.
Program terminated with signal SIGABRT, Aborted.
