System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: GeForce GTX 1060 6GB/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 460.89

Blender Version
Broken: version: 2.93.0 Alpha, branch: master, commit date: 2021-02-21 00:52, hash: 4dd782a1a3

Short description of error
In the 3D view you have a red border around an active render border. In the Image editor not.

This can lead to hours of lost render times since you cannot see if a render border is active or not. And is inconsistent. Two equal functionalities should work equal.

Exact steps for others to reproduce the error
Open Blender, activate Render border in the 3D view and render a portion with viewport shading rendered.
Now render the image, and render a portion of the image with enabled render border. You will notice that in the 3D view you have a red rectangle that indicates that the render border is active and what area to render.

But in the image editor you just see that just a portion is rendered. The next render can be with or without render border. There is no visual hint if the tool is active or not. And no hint if you have selected the correct area for preview rendering.

Unfortunately, this is not a bug nor a regression. I will mark this as a To Do.

Any guidance on where to make the change(s)? Render border appears in many places :)

I'm giving this one a try! I've made the render border appear as the image renders (progress below), but I'd like to clarify this task. Should the render border:

appear on top of the completed render image, and
update as the user changes the render region of the camera in View3D or in the Render window?
It looks like changing camera attributes or post-processing might make (2) kinda funky.

Mh. Just an oppinion here. But from a user point of view this render border in the image editor should be completely independent from the 3d view. Viewport rendering happens exclusively in the viewport. And you can have a completely independant render region area in the viewport and in the image editor.

I found out there are two render regions accessible from the 3D Viewport, one is used exclusively in camera view and the other is during regular 3D viewing.
@tiles I definitely won't touch the regular 3D view render region, though it looks like the render region in the camera view is already linked to the image editor. I'm using this one to draw the region borders.

Currently, I have a red rectangle drawn in the image editor when the render stops, and it updates as the render region updates.

I see. It's about the code. Thanks for explanation :)
