+Subject: [PATCH 12/48] xwayland: Update regions on texture updates
+
+For X11 clients running on Wayland, the actual texture is set by
+Xwayland.
+
+The shape, input and opaque regions, however are driven by X11
+properties meaning that those may come at a different time than the
+actual update of the content.
+
+This results in black areas being visible at times on resize with
+Xwayland clients.
+
+To make sure we update all the regions at the same time the buffer is
+updated, update the shape, input and opaque regions when the texture is
+committed from when the Xwayland surface state is synchronized.
+
+That fixes the remaining black areas being sometimes visible when
+resizing client-side decorations windows on Xwayland.
