From cb481a66cd3e27845fa5cfe8a775e5d178c6c3b5 Mon Sep 17 00:00:00 2001 From: Daniel Stone Date: Tue, 17 Mar 2020 21:52:28 +0000 Subject: [PATCH] wayland-backend: Fully damage initial SHM buffer In order to start the repaint loop, the Wayland backend tries to damage the full SHM buffer, but doesn't actually damage the full area if we have a frame. Store the buffer's width and height alongside the buffer itself, so we can damage the full area when required.
