--- Comment #19 from Chris Wilson <chris at chris-wilson.co.uk> ---
The issue is:

diff --git a/src/sna/sna_dri2.c b/src/sna/sna_dri2.c
index a8b0db4..ba7b429 100644
--- a/src/sna/sna_dri2.c
+++ b/src/sna/sna_dri2.c
@@ -341,6 +341,8 @@ static struct kgem_bo *sna_pixmap_set_dri(struct sna *sna,
        if (priv->gpu_bo->tiling != tiling)
                sna_pixmap_change_tiling(pixmap, tiling);

+       priv->clear = false;
+       priv->cpu = false;
        return priv->gpu_bo;
 }


But I need to actually worry about this a little more.
