    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.
