Incorrect Auto Texture Space in both viewport and render, and with and w/o modifiers #64739

New Issue

System Information
Operating system: Windows-10-10.0.17134 64 Bits
Graphics card: GeForce GTX 1060 6GB/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 425.31

Blender Version
Broken: version: 2.80 (sub 68), branch: master, commit date: 2019-05-16 17:17, hash: 3076544c8c

Let me know if it's better to split these into multiple bugs. They're just very related, like different expressions of the same problem, and I wanted to show them all at once

Short description of error(s)

A) During render and with a modifier on a mesh, even with Auto Texture Space (ATS) OFF, it will behave as if ATS is ON, and not even in the shape of the original mesh, but one that stretches and bounds the entire modified mesh (eg if a mesh has a mirror modifier, the bounds of the Texture Space is a wide as the final mesh, something that doesn't happen in 2.79) (I haven't tested every modifier)

B) If you were using ATS OFF with custom bound values, and then turn it ON back again, the values of the bound won't update to reflect it until you reload the file or undo. (In 2.79 you could simply enter into edit mode and the values would update) But this has weird consequences for that period in which ATS is ON but the values don't reflect it:

C) During render, and without a modifier, even with ATS ON, it will render with ATS OFF and the old bound values. But if it has a modifier, bug A) happens

D) On the Lookdev viewport however, you can see the correct ATS on the material as soon as you turn it ON, even on meshes with modifers and even though the values of the bound still won't updated. But you realize that it's not truly working when you render and bugs C) and A) happen, or when you enter and exit edit mode and see the old custom Texture Space still working instead of the ATS that we want

All in all, bug C) and bug D) would disappear if bug B) got fixed to update the values more instantly. But that still leaves bug A) Meshes with modifiers during render won't use either the custom texture space nor the ATS of the original unmodified mesh (render engine doesn't seem to matter)

Exact steps for others to reproduce the error
[Based on the default startup or an attached .blend file (as simple as possible)]

Use lookdev or rendered shading mode
To observe bug A) open the file and just render F12. The entire column of objects with modifers will have the wrong texture space
To observe bugs B) C) and D), since these get cured as soon as a file is reloaded, you have to turn off Auto Texture Space on the last two rows of objects, input custom texture space bound values (like Loc0,0,0 Scale 1,0.2,0.2 to use the same I used) and then turn ATS on again. You have to enter and exit edit mode on the last row too and this should replicate the images attached. Observe how the bound values remain the same still.
To observe the ATS updating the bounding values, Save and Reload.

I hope the checkmarks gives you an idea on how things should look properly. With and without modifier, with and without ATS, and the same across viewport and render with no differences

I can confirm that the result differs between viewport and render for both eevee and cycles.

@brecht, @fclem any ideas?
