--- Comment #6 from Marek Olšák <maraeo at gmail.com> ---
We could get a race if vlVdpOutputSurfaceDMABuf is called from a different
thread than the context is normally used with. Can that happen?

You can try to test this:

diff --git a/src/gallium/state_trackers/vdpau/output.c
b/src/gallium/state_trackers/vdpau/output.c
index 64574b2..96474fb 100644

    whandle.type = DRM_API_HANDLE_TYPE_FD;

    pscreen = vlsurface->surface->texture->screen;
-   if (!pscreen->resource_get_handle(pscreen, vlsurface->device->context,
+   if (!pscreen->resource_get_handle(pscreen, NULL,
                                      vlsurface->surface->texture, &whandle,
                                     PIPE_HANDLE_USAGE_READ_WRITE))
       return VDP_STATUS_NO_IMPLEMENTATION;
