System Information
Operating system: Windows-10-10.0.19045-SP0 64 Bits
Graphics card: NVIDIA GeForce GTX 1060 6GB/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 527.56

Blender Version
Broken: version: 3.6.0 Alpha, branch: main, hash: 893bd37bc035
Worked: 3.5.1

this apparently broke with 0de54b84c6

Short description of error
Updating of some node editors cause graphic artefacts if it happens during cycles rendering.
Video example is attached.

Exact steps for others to reproduce the error

  1. Use Cycles render.
  2. Start final render.
  3. Do something with any node editor.

I am not sure if this has been triaged correctly. I would expect that this has been confirmed by someone to be reproducable. and performing a bisect. This points better to which module should take ownership of this issue.

Also not sure why this was marked a high priority by the reported. Perhaps it was discussed, but I don't see any paper trail.

I can reproduce as well (and will do a quick bisect).
In my case, I am getting a completely black node editor until rendering finishes.

I do think though that this has been triaged correctly, it was reproduced, it was checked that this is a recent regression (and that alone makes it a high priority issue), doing bisects sort of became a good habit by the triaging team (it is not mandatory though to have a report triaged correctly).

For me, this broke with 0de54b84c6

Will leave it up to the modules to decide who is responsible.

Pretty sure it's caused by https://projects.blender.org/blender/blender/src/branch/main/source/blender/editors/space_node/node_draw.cc#L3408
I'll have a closer look. That was introduced because baking might change data that is read during node editor drawing.

@JacquesLucke this can introduce the mentioned artifacts.
Not sure if baking or displaying could work on a localized copy and flush when frame finished?

Note I change the Module to Nodes&Physics for clarity. If you need any help, let us know!
