backtrace
I consistently see a segfault in _gdk_wayland_cursor_set_scale using an app
(virt-viewer). cursor->name is NULL and g_str_equal tries to dereference it,
see backtrace attached. This is with 3.22.4, but should happen in master as
well.
Commit <a href="https://git.gnome.org/browse/gtk%2B/commit/?id=db49d12fcf3">db49d12fcf3</a> standarized the name of blank cursors to "none" in
_gdk_wayland_display_get_cursor_for_name_with_scale.
I assume the problem is that _gdk_wayland_display_get_cursor_for_surface can
still create a blank cursor with NULL name.</pre>
