[clutter] How to stop ClutterTexture from alpha blend with background color?

[Malluru, Puri]

Hi

I am loading a screen from a json file like the one attached at the end
of this email. When the object "nearvideo" gets loaded into a stage
whose background was set to black, the image "nearvideo.jpg" is getting
alpha blended with the background color and shown.

What to do to make it look as is without alpha blending with background
color?
