Worked: 2.90

Exact steps for others to reproduce the error
In this .blend file
compositing_291_bug.blend
there are 3 scenes, each with a different object, that are overlayed in compositor.

Open the file and render (F12).
If you're seeing 3 objects that means compositor worked.
Try render (F12) again. It may take couple of attempts but eventually you should see that there is now only monkey object from scene 3 rendered.
If you still can't reproduce, you can also try to 'maximize' the image view window. I noticed that it may trigger the bug, but could be a red herring.
Now change "Layer" from "Composite" to "View Layer"
And then back to "Composite".
All three object are now rendered.

A bit weird, I have seen this a couple of times, but I cannot reproduce it reliably.
(in that sense, it reminds of #81775 (Crash on Exiting Texture Paint With Multiresolution (Image Editor involved)) - where the image Editor is also involved).

Will confirm for now.

@MarcinTwarowski : is this the same for on every run? (Once I even had this on the first render)

I can reproduce it every time. I just reopened Blender couple of times, and it failed to composite on:

4th F12
5th F12
3rd F12
3rd F12

My first impression is that the texture on the GPU needs to be refreshed and that isn't working properly. Will add it to my list to research.

This issue has been fixed. I assume some of the tweaks in the threading solved this issue.

Something has changed in 3.0. It seems to be partially fixed. I just tested with:

Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: NVIDIA GeForce GTX 1080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 466.77

version: 3.0.0 Alpha, branch: master, commit date: 2021-06-13 23:56, hash: `rB54a03d4247cc`

Notice that on the first render it fails to composite. On every subsequent render it works fine, though. This happens every time:

Desktop 2021.06.14 - 13.20.49.02.mp4
