--- Comment #65 from Chris Wilson <chris at chris-wilson.co.uk> ---
To be honest, I had hoped that this would have proven to be the unfenced-BLT
bug. The known w/a for UXA is to enable DebugWait, which implies that UXA is
not handling its domains correctly.

The most likely candidate is:

diff --git a/src/intel_uxa.c b/src/intel_uxa.c
index 76a3146..40e3b67 100644
--- a/src/intel_uxa.c
+++ b/src/intel_uxa.c
@@ -1379,8 +1379,8 @@ Bool intel_uxa_init(ScreenPtr screen)
        }

        /* PutImage */
-       intel->uxa_driver->put_image = intel_uxa_put_image;
-       intel->uxa_driver->get_image = intel_uxa_get_image;
+       //intel->uxa_driver->put_image = intel_uxa_put_image;
+       //intel->uxa_driver->get_image = intel_uxa_get_image;

        intel->uxa_driver->prepare_access = intel_uxa_prepare_access;
        intel->uxa_driver->finish_access = intel_uxa_finish_access;
