Is this a bin/manta problem or something in the MantaInterface implementation? The code that dumps frames to disk (for camera path animation) replaces the OpenGLDisplay with a MultiImageDisplay, where one of the child displays is the original gl display and the other is some type of file display.

It might be the case that a separate channel is being setup for each -imagedisplay on the command line. I'm not sure why this would be useful to bin/manta which only displays one window.

It may have served some purpose in the beginning (adding more multiple displays), but I don't think it works as intended.  I think for the sake of simplicity, this behavior should
be seen as a bug and fixed.

Thanks,
