From 434e7f0e87c7728ad2c9056ee4cf42686db2d5f2 Mon Sep 17 00:00:00 2001 From: Michael Tretter Date: Thu, 23 Aug 2018 16:58:47 +0200 Subject: [PATCH 3/3] 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.
