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