Please ensure you have installed the latest driver version from the Intel website, the last one I can find is 26.20.100.7000:
https://downloadcenter.intel.com/download/28991/Intel-Graphics-Windows-10-DCH-Drivers?product=88359

If that doesn't help, please attach a simple .blend file to reproduce the problem.

Thanks for an answer! If I try to install downloaded drivers from location you mentioned, I get and error. Description:
- Error Message: Computer Manufacturer Graphics Driver Detected
- Your computer manufacturer customizes drivers that run Intel® components on your machine.
My PC is notebook Acer Aspire F 15.
But actually I have the same problem on a desktop (another PC).untitled.blend

Some additional information.
I borrowed nVidia GeForce 710 videocard for experiment and put it in desktop, rendered default cube as intended, without bugs.
So problem exists on both of my systems:
Intel(R) Iris(R) Graphics 550 (notebook)
Intel(R) HD Graphics 610 (desktop)

I had the same problem and posted about it. It seems to be related to using CPU + GPU.
CPU OR GPU works, but not together. Disabling CPU makes the bug disappear. If I can reproduce the bug I will post it here, it only happens every 2-3 days for me.

I wonder how much time would it take to get an answer. 'Needs Triage by Developer' is good, but is it possible to be more specific. Thanks

@Tonic-1 Is this still an issue with latest build? https://builder.blender.org/download/

Yes, it is. Version 2.82.6, just it checked on Intel(R) HD Graphics 610 (Win 10 desktop).

I was looking back over random reports and found this. The report lists CPU+GPU rendering as the cause for the issue but it seems the user is rendering with their CPU plus integrated Intel graphics. Isn't this a un-supported configuration?

This is not a Cycles issue, what @Muritaka reported seems unrelated to this bug.

Might be unrelated, but Tile artifacts with transparency can also be seen in #53334 (particles + motion blur cause artifacts)

Did the issue go away with 2.83? can you reproduce with 2.90 alpha? what if you run blender using the force-workaround batch file?

What is the system-info.txt of the desktop?

The driver of the laptop is really old and is known to have issues.

Don't know. See, I have 2.80.75:
Considering desktop - blender doesn't start anymore. Error message: "Blender - Unsupported Graphics Card or Driver [skip]"
Considering laptop - bug went away without either blender or driver update!

can you reproduce with 2.90 alpha?

Desktop - doesn't start

what if you run blender using the force-workaround batch file?

I didn't try

What is the system-info.txt of the desktop?

I can't get it

The driver of the laptop is really old and is known to have issues.

I didn't update driver, but issue mysteriously went away by itself

Thx getting back!

Dont think there is much we can do then unfortunately...

Considering laptop - bug went away without either blender or driver update!

That is great to hear, I think we can close this then?
