Glyph3D Representation opacity is broken

Glyph3D Representation does not behave as expected.

Changing the opacity actually changes the color intensity.

Steps to reproduce:

Open ParaView
Create Wavelet
Show with Glyph3D representation
Color with RTData, Show color map editor
Modify opacity parameter from 1 to 0.99 -> representation changes a lot, not as expected
Lower opacity to 0.5 -> Color starts to disappear, revealing while model underneath, not as expected
Lower opacity to 0.1 -> Color disapear completelly, all is white, unexpected
Set opacity to 1 -> 3D glyphs are correctly rendered with an opacity of 0.1 (last used opacity), not as expected
Change the color map slightly -> 3D glyphs are rendered with an opacity of 1
