This should hopefully fix it:

    videomixer: fix warnings when using transparent background

    gst_video_frame_map() increases the refcount, which makes
    the buffer not writable any more technically, so calling
    gst_buffer_memset() on it will cause nasty warnings.

    Unit test disabled because it very rarely (for me)
    fails, possibly negotiation-related.

What's the other problem ? Did you file a bug for that? (the unit test
sometimes fails, might be the same).
