<pre>Way to reproduce:
- weston backend closes current output and creates new one.
- old weston_output structure is released.
- compositor views have pointers to old weston_output.
- these pointers became dangling.
Fix:
in weston_compositor_remove_output(...) add resetting reference to output:
wl_list_for_each(view, &compositor->view_list, link) {
if (view->output == remove_output) {
view->output = NULL;
view->surface->output = NULL;
}
}</pre>
