+Subject: [PATCH] gdk/x11: Invalidate whole surface after size change
+
+The Expose events following a ConfigureNotify may arrive at
+a time that we did not resize the surface yet, making these
+expose events a no-op. Even though gsk/gtk take care of the
+window content itself, this might lead to unrendered portions
+of the window shadow.
+
+This may be seen with GSK_RENDERER=cairo and GDK_BACKEND=x11,
+attempting to tile a window (e.g. gtk4-demo) left or right.
+The window will show black rectangles or other artifacts in
+the window shadow areas that correspond to the newly painted
+portions (as the window needs to expand vertically).
+
+In order to fix this with a similar behavior to Wayland,
+consider ourselves the whole surface invalidated after resize,
+in order to ensure everything is painted from scratch.
+
+(cherry-picked from commit 24302315fb8f46be141a9eda60e8d107c84a948d)
