From 325ff4cba1e9c9bc15c36b960cf892c7633ce4dd Mon Sep 17 00:00:00 2001 From: Pekka Paalanen Date: Mon, 23 Apr 2018 11:44:59 +0200 Subject: [PATCH] main: add setting for DRM/pixman shadow framebuffer Allows to control the Pixman-renderer shadow framebuffer usage from weston.ini. It defaults to enabled, and whether it is a good idea to disable or not depends on the platform and the workload.
