There's no synchronisation point in dri3 with X:

diff --git a/src/loader/loader_dri3_helper.c b/src/loader/loader_dri3_helper.c
index a55719a..6b5736b 100644
--- a/src/loader/loader_dri3_helper.c
+++ b/src/loader/loader_dri3_helper.c
@@ -1399,6 +1399,7 @@ loader_dri3_get_buffers(__DRIdrawable *driDrawable,
       buffers->back = back->image;
    }

+   loader_dri3_wait_x(draw);
    draw->stamp = stamp;

    return true;

brings it into line with dri2.
