From f28c56ee3ef9147ffe887cfdc7903facf718677d Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jonas=20=C3=85dahl?= Date: Mon, 23 Jul 2018 21:36:57 +0200 Subject: [PATCH] renderer/native: Check calculated transform when creating view The "backends: Move MetaOutput::crtc field into private struct" accidentally changed the view transform calculation code to assume that "MetaCrtc::transform" corresponds to the transform of the CRTC; so is not the case yet; one must calculate the transform from the logical monitor, and check whether it is supported by the CRTC using meta_monitor_manager_is_transform_handled(). This commit restores the old behaviour that doesn't use MetaCrtc::transform when calculating the view transform.
