+Subject: [PATCH] meta-surface-actor: Fix is_argb32 for unredirected windows
+
+meta_surface_actor_is_argb32 assumes that lack of stex means that a window is
+ARGB32. When we unredirect a window we detach the texture so we end up without
+a texture. Given that should_unredirect returns FALSE when a window is argb32,
+we know that this window is indeed not ARGB32.
+
+Returing TRUE in that case causes us to flip between redirected and
+unredirected on every paint.
+
+So fix that by returning FALSE in that case.
