@h99 in your file the white is not shown at all…
i fear that understanding the blend function is not so trivial. so here i made comments in the patch to explain what happens to the pixel buffer when you blend the different layers into it.
the trick is to start with a pixel buffer with all alpha set to 0. then let the text write something into the alpha channel and use that to blend the other two quads:

tonfilm you are the boss !
always got lucky with alpha blending so far without knowing what I was exactly doing…so thanks a lot for your greats explanations !!!
