   4 Subject: [PATCH 3/3] compositor: do not request repaint in output_enable
   5
   6 When enabling a weston_output, the compositor damages the entire output,
   7 to ensure that the entire output is redrawn. However, this triggers a
   8 repaint, which might happen before anything is actually drawn. The
   9 result is a black frame before the shell is displayed.
  10
  11 Damage the entire output region, but do not trigger the repaint when
  12 enabling a weston_output.
