Re-reporting of #72371 since it was closed for... not getting around to respond for two weeks?? o.O;;

System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: GeForce GTX 1080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 432.00

Blender Version
Broken: version: 2.83 (sub 0), branch: master, commit date: 2020-01-14 20:45, hash: 1ec08999b6
But really, it's been broken on any 2.8 series for me.

Short description of error
Unsure exactly what I did, but a file I was working on refuses to update changed World values in real time in the viewport.

However, if I toggle "Use Nodes", the values update.

I was messing with the "Easy HDRI" add-on some time ago in this scene. I don't know if that caused the glitch somehow, but I thought I'd note it just in case.
Here's the file stripped down to the essence to test.
LightingGlitchTest2.blend

Exact steps for others to reproduce the error

Open up the above .blend file
Change the 3D view (only the one under properties editor) to "Rendered"
Try changing/modifying the world values/nodes (e.g. the value of the "Add" node in the node tree).
If the problem is there, you'll find that the "Rendered" viewport doesn't update unless you toggle "Use Nodes" for the World.

Seems to be updating correctly here:

Could you check if upgrading you GPU driver works?
Also: please check if this is happening with Factory Defaults as well?

This seems to work only if viewport under nodes is switched to rendered view.
So I can confirm.

This also updates correctly for me in Material Preview mode (if I set the Viewport Shading options to use Scene World)

@iss: it doesnt for you?

Ah, see the problem now, if only the viewport under the properties editor is set to either Rendered or Material Preview (and the viewport under nodes isnt), it doesnt update, can confirm.

No, following steps as I updated them does not result in viewport to updating in real time.

I can see pixels "twitching" when I change values in node editor, so it definitely does redraw

I can cause update when I change cfra manually, but not while "playing animation"

Issue is related to when the World background shader is invalidated. When there are 2 EEVEE renderings in the same window EEVEE might not detect the differences and still think that the world shader is correct.
Will need to look into a better solution for EEVEE_lightprobes and `EEVEE_lookdev``

Thanks so much for figuring out the issue! I had no idea it happens when only the viewport under the Properties panel is changed to "Rendered" view, but glad the issue has been confirmed.

I reproduced this in a more simplified report, so closing this for now.
