Subject: Expose events can be called on windows that have already gone out of scope

I think this one needs a proper test case to confirm the behaviour I'm seeing, but: $event_ids->{expose} = $window->bind_event( expose => sub { my ( $win, undef, $info ) = @_; $win->is_visible or return; $info->rb->setpen( $self->{pen} ); $self->render_to_rb( $info->rb, $info->rect ); }); That $win->is_visible check can fail with this: Error: Can't call method "is_visible" on an undefined value at .../Tickit/ line 526. which I think was triggered by this: my $win = ...temporary window with refcount 1...; $tickit->later(sub { $win->expose }); # immediately after the ->expose call, $win goes out of scope so the window refcount drops to zero Changing that line to check for '$win && $win->is_visible' instead seems to be enough to fix it.
