Hmm. I think that means that sna_pixmap_get_buffer() is NULL, if so the full
debug log will just explode as well. Quite possibly that it is NULL after a
composite redirect - I will have to think about that.

If you apply

diff --git a/src/sna/sna_dri2.c b/src/sna/sna_dri2.c
index fd3edcc..1c26131 100644
--- a/src/sna/sna_dri2.c
+++ b/src/sna/sna_dri2.c
@@ -150,6 +150,8 @@ sna_dri2_get_back(struct sna *sna,
        int flags;
        bool reuse;

+       assert(sna_pixmap_get_buffer(get_drawable_pixmap(draw)));
+
        DBG(("%s: draw size=%dx%d, buffer size=%dx%d, is-scanout? %d, pitch=%d,
front pitch=%d\n",
             __FUNCTION__, draw->width, draw->height,
             get_private(back)->size & 0xffff, get_private(back)->size >> 16,

and compile with --enable-debug (no need for =full, we just want to enable the
assertions), that will confirm the theory.
