Cycles viewport render border no longer shows scene behind with OpenGL
Confirmed, NormalPublicTO DO

Description

System Information

Blender Version
Broken: rB42dd888b98b598c240f78302b857fa60add08ca5

Short description of error
Cycles Preview render removes all shading from the scene. This is very evident when using border renders to help isolate down sections to work on (which is key for working on large scale production scenes.

Exact steps for others to reproduce the error

  1. Open attached blend file in blender 2.79
  2. hit shift z in the 3d viewport
  3. notice how you can see the building to the left
  4. close blender 2.79, and open the attahced blend file in blender 2.8
  5. hit shift z in the 3d viewport (blender 2.79 keymap)
  6. notice how you cannot see the building to the left anymore?

This means that reframing whilst border rendering is no longer possible, nor is it possible to change the border render without guessing to work on a different area of the frame without having to go back to solid mode and then back to rendered mode. Going in and out of solid mode can be 20-30 seconds on production scenes so limiting the amount of switching is important.

@Brecht Van Lommel (brecht): I think this has been reported before? (cant find it atm).
Personally I find this distracting as well. Is there anything that keeps us from remaining in the same shading mode [that we were in before switching the "rendered"] for the rest of the viewport?
(think this is how 2.79 did it)

Sebastian Parborg (zeddb) lowered the priority of this task from 90 to 50.

Just wanted to confirm the importance of this bug, as it breaks my whole workflow. Just another real-life example. I work with product rendering and use mesh lights for lighting / reflections. Those lights are not displayed to the camera. I work with border rendering mostly permanently ON when it comes to lighting the scene, and framing only the product allows me to move the mesh lights and see how the reflections and lighting change in real-time.
In 2.80 I'm forced to double-window as the planes are no longer visible in the main-viewport. Working with two windows is very un-intuitive and slows down my workflow five-fold or even ten-fold, as I have to do a lot more zooming-in, panning, etc. To me, this is a deal-breaking bug which prevents me from using 2.80 altogether.

Would be great to have the behaviour form 2.79 back!

I can't wait till this is fixed as well. That makes work really inconvenient.

Any news on this? Any chance of it being fixed for 2.81?

I add my vote for this too, it's much needed months and months passing by without any fix yet.

Much need! This feature is one of the main reasons I switched to blender.
