The client bug is: https://github.com/wez/wezterm/issues/2445#issuecomment-1502516313 - it will set (and commit) a buffer_scale of 2 while having a buffer with dimensions not a multiple of 2 committed in some circumstances. GNOME Shell (correctly) sends a protocol error, and disconnects the client. However, when dragging the window from a scale-1 output to a scale-2 output with the mouse, gnome-shell will kill the client with a protocol error, but then immediately crash. I've tested killing a gnome-text-editor client with SIGTERM while moving the window with the mouse, and that *doesn't* kill gnome shell, so this doesn't appear to be just a matter of a client disconnecting while their window is currently mouse-dragged.
