I have an "empty" plane in which I am displaying an image. In Blender 2.80 this object seems to have trouble interacting with transparent objects in the 3D view, although this technique worked in Blender 2.79. In the following example, the entire blue sphere should be visible, as seen in the first image where it has alpha = 1.0. But when alpha < 1, the "empty" image behaves as if its "always in front" setting is activated, but only with the transparent object, not with fully opaque objects.
The sphere color is set as sph.diffuse_color = [0.0, 0.3, 0.8, 0.5].
The image is a grayscale tif, loaded into an "empty" plane.
Is there setting I am missing, in order to tell the "empty" image to interact properly with transparent objects in the scene?
