Green Artifacts When Viewing Shared Screens in Teams

As of my information I got today from Microsoft Support, this problem is now finally solved.

Original Information from Microsoft:
I'm pleased to inform you that a fix was recently deployed. This was handled directly by our Product Group, and it has been confirmed that the issue is fully resolved.

Current Status: We suspect that the impact was caused by a recent update to a specific third-party driver, which led to some users experiencing a green screen during Microsoft Teams meetings. We deployed a configuration change to bypass the impacted drivers, and we now have confirmation that this change has resolved the issue.

Final Status: The investigation is complete, and we have confirmed that the issue was caused by a specific third-party driver update. Our fix has resolved this, and this communication will expire in 72 hours.

This is the final update for the event.

We concur that the issue should no longer exist, as you had affirmed from your boss. Therefore, I believe that the remote session might not be necessary, and I am quite confident that it won’t occur again.

-> It was fixed by the backend Infrastructure thus our Product Group. So no Update required on an End-Device for this issue.

My customer did not face the issue in the last two days - so this time, I really hope it is finally fixed.
Please let me know if you are still facing the problem - or if it is also fixed for your environment - so everybody reading this thread finds the final answer.

We got the same issue here. Green artifacts on the stream during Teams Meetings and also on some web streams in Edge/Chrome browsers.

This happens on 2 new Dell Latitude 7350 devices. (Our first devices with an Intel Core Ultra series CPU.)

Specs:

Dell Latitude 7350

Intel Core Ultra 7 165U

Integrated Graphics

16 GB LPDDR5x memory

512 GB NVMe SSD

Installed Intel graphics driver:

32.0.101.6449

Note: We skipped 32.0.101.6458 as there has been no relevant info in the changelog.

BIOS version: 1.11.1 (from 14 January 2025)

Both devices have been newly installed with Windows 10 Enterprise. The existing installation from Dell has been wiped before. (diskpart -> clean)

Note: Windows 11 is still on our to-do list for this year and no option yet due to old software on a server.

What we tried so far:

• Checking out the proposed edit to the "Desktop-config.json" file. - This will not work with Team (New) though as it does not create a Teams folder under "C:\Users%username%\AppData\Roaming\Microsoft" anymore. Any remnant folder is most likely from a previous Teams (Classic) installation.
• Disabling hardware acceleration for WebView2 via environment variable using "setx WEBVIEW2_ADDITIONAL_BROWSER_ARGUMENTS --disable-gpu". - Initially this seemed to work but the issue soon happened again afterwards.

Source (regarding disabling hardware acceleration in Teams):

What seems to currently work as a temporary "fix":

• Disable hardware acceleration entirely on the user via registry, then reboot once. HKEY_CURRENT_USER\SOFTWARE\Microsoft\Avalon.Graphics\DisableHWAcceleration DWORD value = 1

Obviously far from ideal. Our issue (aside from the main issue itself) is that Teams (New) does not have the "Disable hardware acceleration" option anymore which was still available in Teams (Classic).

And we would have needed to disable hardware acceleration specifically for Teams (New), Edge, Chrome and Firefox for our use cases.

So far we believe Intel probably has to fix this issue since disabling hardware acceleration seems to bypass it but the earliest (similar) post we found regarding Intel Core Ultra series artifacts is from November 2024... this might be a long one - assuming that this is related to the "current" issue somehow.

Thanks Alex.Re,

Microsoft is also working on this, I have an open Support case with them. They informed mw today:

"Due to the influx of issues on this very nature, we confirmed this to be a service Degradation and currently working with other affected clients to narrow down the issue and deploy a fix shortly."

So it could be that there is also a fix from Microsoft on its way - but I have not further information as of now.

Yes, unfortunately also at my customer, this latest Windows Updates did not solve the problem.

If anyone has had any success with it - please let us know.

Meantime I informed my Microsoft Support Engineer from that open case twice today already and asked for further help.

Same problem here with a new HP Zbook Power 16 G11, 16" WQXGA, Intel Ultra i9 185H, 64GB Ram, 2TB HD, Nvidia RTX 3000 - one of the most powerful Notebooks on the market today.

I will attach a print screen from the video's so everybody can identify it. (some areas are normally blurred so the person can not be identified). the problematic Videos are mostly green and marked with red arrow)
