System Information
Operating system: Win10
Graphics card: RTX2060(laptop)

Blender Version
Broken: 2.93

Short description of error
I'm making a short film for my animation project. Every thing looks good in the viewport but it will randomly glow up some sparks looking flash when rendered.
Render_04.mp4
Event without composting.
Render_04_Original.mp4
I thought that it might caused by bloom, so I tried to disable it. But it still pump up some overexposed areas in the image. Which is confuses me.
And I'm not sure if it is the EEVEE renderer error or my animated shader causing it error.
Hope it can be found and fixed.
AnimeTrain_Debug.blend

Exact steps for others to reproduce the error
Just make sure you are in EEVEE and hit render animation.

Not checked the file yet. Can you replicate the issue with more simpler file?

Unsure but the problem could be similar to #86578 (white artifacts in EEVEE)

It's quite similar, but it happens randomly throughout the scene.
Test_01.mp4
I can hardly find any pattern of it, and it doesn’t seem to be caused by AO or normal map.
Even if I remove the station and train, it still appears in the background.
Test_03.mp4
Here's the simplified version.

This looks very similar to this known issue with RTX cards. #77202
Can you try disabling/removing all volumes from the scene to confirm if it is related?

Indeed looks same as #77202

@SoGoodAndTasty, please check if that works
