--- Comment #1 from Nate Graham <nate at kde.org> ---
#6  QMessageLogger::fatal (this=this at entry=0x7fffd70c5ba0,
msg=msg at entry=0x7ff994ac00b8 "The Wayland connection broke. Did the Wayland
compositor die?") at global/qlogging.cpp:893

This means that the compositor crashed. Due to a Qt issue, when this happens,
the app using it will crash too. KDE developers submitted a fix, but sadly it
was not merged. See https://codereview.qt-project.org/c/qt/qtwayland/+/308984.

Until we get better handling of this in Qt, the best we can do is debug why the
compositor crashed in the first place. So can you please get a backtrace of the
crash in kwin_wayland and then file a new bug report with it on kwin |
wayland-generic? Thanks!

You may be able to use the `coredumpctl` utility to retrieve the backtrace. See
