shell: Fix artifacts caused by workspace change animation
Views that extend past the bottom of the output are still visible after the workspace animation ends but before its layer is hidden. When the layer was hidden, nothing would cause those regions to be repainted, leading to artifacts. https://bugs.freedesktop.org/show_bug.cgi?id=78363
