Thanks @zebus3d and I agree that they should try to fix the empty image on Wireframe Mode, after all this will be our main workflow now that they are replacing background images.
This is a list of things that could be improved or fixed on 2.8 regarding Empty Images and Intersecting objects, according to the above investigation:
Fix the wireframe not showing on top of the Empty Image even when X-Ray Slider is On.
Fix wires not appearing behind intersection of an empy-image even when X-Ray Slider is set to 1:
Improve visibility of semi-transparent meshes, at least to 2.79 levels… currently it’s incredibly dithery, to the point that it completely hides whatever it’s behind the dither and hurts visibility:
(I’m pretty sure on that cut area of 2.8 we have more dither pixels than dinossaur pixels )
Regarding Transparent Images mapped to Plane objects:
IMPORTANT: Fix the In Front option on LookDev mode, so that it renders the object selected completely on top of any other object. (Render on top independently of the Display As render option)
Maybe add some way of viewing the transparent shaded objects in Wire and Solid Modes as well. (Currently can only see them transparent on LookDev and Rendered modes or if it’s an empty image).
