If you apply

diff --git a/src/sna/sna_accel.c b/src/sna/sna_accel.c
index 2513b8b..fcf354e 100644
--- a/src/sna/sna_accel.c
+++ b/src/sna/sna_accel.c
@@ -4556,7 +4556,7 @@ try_upload_tiled_x(PixmapPtr pixmap, RegionRec *region,
                return false;
        }

-       if (priv->gpu_damage &&
+       if (priv->gpu_damage && 0 &&
            region_subsumes_damage(region, priv->gpu_damage)) {
                if (UNDO)
                        kgem_bo_undo(&sna->kgem, priv->gpu_bo);

that will disable one chunk of that patch. Does the corruption still occur?
