From 878df84bdfa612d2b095521ad1a75ba9f873cc7f Mon Sep 17 00:00:00 2001 From: Damian Hobson-Garcia Date: Mon, 29 Mar 2021 17:43:49 +0900 Subject: libweston: Don't request repaint in output enable Allow for the compositor to start without first displaying a blank screen when no startup transition is used. This patch is under review in the mainline weston repository. It should be useable for other use cases besides drm-lease, but right now this patch causes the weston test suite to fail by unconvering an unrelated problem with wayland event handling[1]. For now, keep this with the drm-lease support under agl-devel until the weston test suite issue is resolved and the patch is merged upstream.
