I'm afraid that's an inherent issue of textured video, as in contrast to
a video overlay the video and other elements overwrite each other.

This probably works due to double buffering. In the future this may be
possible with XVideo as well by using a pixmap as the 'back buffer', but
it's not implemented yet, though somebody posted a patch for it to an
upstream mailing list a while ago.

Using textured video as well, not an overlay?
