PCB Editor layer transparency not working right

PascalVM

I'm trying to get the top copper layer, solder mask, and paste masks to show together. This is usually always worked for me and the colors are blended together.

However now I'm looking at a board that doesn't do that if the pad size of the layers is identical. I checked a different board and it was the same problem, I think it's a global thing.

For example I have the solder mask selected red and the paste mask selected yellow. When the solder mask is a little bit larger than the paste, the colors are blended together as orange. However if the pad is the same, then I only see yellow even though I know there is red under it.

If I change the transparency sliders, it will change the overall transparency but still doesn't blend the colors of 2 or more visible layers. How can I fix this?

    I don't believe this has ever been the case (but I could be wrong) If the pad layer size is the same for all layers, it always shows the active class/subclass as the most prominent layer color. You can change the top most visible one by setting the Active Class / Subclass in the Options pane but you will only see a blended color if the pad layers are different sizes. I did try this in 16.6-2015 and got the same result as 17.2-2016.
