Title:
gnome-shell crashed with SIGSEGV in wl_resource_add_destroy_listener()
from meta_wayland_keyboard_set_focus() from
meta_wayland_seat_set_input_focus()
Status in Mutter:
Fix Released
Status in mutter package in Ubuntu:
Confirmed
Bug description:
GNOME Shell reliably crashes when I drag a (buggy) Wayland client from
a scale-1 output to a scale-2 output.
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.
