I want to apply a jit.gl.slab (cc.brcosa.jxs) in a jit.gl.videoplane with blend_enable 1. The problem is that if apply the slab, the clip on the videoplane lost some oppacity. But if blend_enable is set to 0 works perfectly, but I need to set to 1 beaucause I need to disolve the videoplane with the alpha channel.
