From 339d56bf5152ae317d7ddd458c042ba632003a23 Mon Sep 17 00:00:00 2001 From: Sergey Sizonov Date: Fri, 8 Dec 2017 19:45:58 +0300 Subject: [PATCH] implement new mechanism for smooth transition from DEVICE to CLIENT This implementation is based on the list of composited hwc_wnds passed along with target_surface these hwc_wnds are composited at.
