Otherwise we'll have a cursor sprite backed by a surface that no longer exist. This usually doesn't happen, but can happen in rare situations related to pointer capability changes Wayland client cursor changes and hotplugs. Fixes the following crash: #0 meta_wayland_buffer_get_resource() at ../src/wayland/meta-wayland-buffer.c:128 #1 realize_cursor_sprite_from_wl_buffer_for_gpu() at ../src/backends/native/meta-cursor-renderer-native.c:1649 #2 realize_cursor_sprite_for_gpu() at ../src/backends/native/meta-cursor-renderer-native.c:1869 #3 realize_cursor_sprite() at ../src/backends/native/meta-cursor-renderer-native.c:1887 #4 meta_cursor_renderer_native_update_cursor() at ../src/backends/native/meta-cursor-renderer-native.c:1100 #5 meta_cursor_renderer_update_cursor() at ../src/backends/meta-cursor-renderer.c:414 #6 meta_cursor_renderer_force_update() at ../src/backends/meta-cursor-renderer.c:449 #7 update_cursors() at ../src/backends/meta-backend.c:328 #8 meta_backend_monitors_changed() at ../src/backends/meta-backend.c:338 #9 meta_monitor_manager_notify_monitors_changed() at ../src/backends/meta-monitor-manager.c:3590 #10 meta_monitor_manager_rebuild() at ../src/backends/meta-monitor-manager.c:3678 #11 meta_monitor_manager_native_apply_monitors_config() at ../src/backends/native/meta-monitor-manager-native.c:343 #12 meta_monitor_manager_apply_monitors_config() at ../src/backends/meta-monitor-manager.c:706 #13 meta_monitor_manager_ensure_configured() at ../src/backends/meta-monitor-manager.c:779 #14 meta_monitor_manager_reconfigure() at ../src/backends/meta-monitor-manager.c:3738 #15 meta_monitor_manager_reload() at ../src/backends/meta-monitor-manager.c:3745 or the following on gnome-43: #0 meta_wayland_surface_get_buffer at ../src/wayland/meta-wayland-surface.c:441 #1 meta_cursor_sprite_wayland_get_buffer at ../src/wayland/meta-cursor-sprite-wayland.c:83 #2 realize_cursor_sprite_from_wl_buffer_for_gpu at ../src/backends/native/meta-cursor-renderer-native.c:1612 #3 realize_cursor_sprite_for_gpu at ../src/backends/native/meta-cursor-renderer-native.c:1836 #4 realize_cursor_sprite at ../src/backends/native/meta-cursor-renderer-native.c:1854 #5 meta_cursor_renderer_native_update_cursor at ../src/backends/native/meta-cursor-renderer-native.c:1087 #6 meta_cursor_renderer_update_cursor at ../src/backends/meta-cursor-renderer.c:413 #7 meta_cursor_renderer_force_update at ../src/backends/meta-cursor-renderer.c:448 #8 update_cursors at ../src/backends/meta-backend.c:344 #9 meta_backend_monitors_changed at ../src/backends/meta-backend.c:354 Related: https://bugzilla.redhat.com/show_bug.cgi?id=2185113 Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2968>
