When I share my screen from Teams my participants see a magenta or green color overlayed randomly across the content I'm sharing. Not constantly, but with flashes. It's very distracting.

This is what it looks like (images made with photoshop as it's hard to press print-screen at the exact right time):

Managed to capture it live in the New teams client:

Here's a video that shows the issue while it happens.

I can easily reproduce the issue:

  1. Start a call from the Teams client (new or classic) and join my main workstation (AMD ThreadRipper 2950X with AMD RX 6750X video card)
  2. Join the call from another system using the windows Teams client (classic or new)
  3. Join the call from another system using the Linux or Web Teams client
  4. From the main workstation (1) start screensharing.
  5. If the issue doesn't appear stop screen sharing and start again.
  6. The users joining from the web client and windows client will not get random flashes of color overlayed over the shared screen.
  7. Not all users see the same flashes at the same time.

The main workstation remains unaffected, it doesn't see any artifacts.

I cannot reproduce the issue while sharing screen from my laptop which has a very similar configuration: AMD Ryzen 9, AMD RX 6500M.

A screen capture utility (snagit) on the affected systems also doesn't capture the artifacts. Taking a screenshot (PrtScn) at the exact right time will work.

I've already tried:

  • resetting my graphic drivers
  • clearing Teams' cache and settings folders
  • reinstalling Teams completely
  • sharing the screen an app or a region doesn't seem to matter
  • replaced the graphics card from an older AMD RX580 GPU to an AMD RX 6750 XT
  • and Dism /Online /Cleanup-Image /RestoreHealth and sfc /scannow
  • all video effects & background blur is turned off.
  • Changed the GPU support settings in Windows and AMD Adrenalin.
  • set disablegpu: true in the %Appdata%\Microsoft\Teams\desktop-config.json config file.
  • Reset all my video codecs to system default.
  • uninstalled the video driver and using Windows-default
  • reinstalled the latest AMD Adrenalin Edition
  • tried with camera and sound disabled.
  • installed latest K-lite codec pack with recommended settings
  • deleted and reinstalled teams completely
  • Tried Teams New and Teams Classic

Most important datapoint

  • The issue occurs when one of the participants is using the Web or Linux client.

  • If you have an HDR monitor, try turning the HDR setting off in Windows to see if that makes a difference.

  • Weird problem. Try to test Windows integrity on that computer by running the commands Dism /Online /Cleanup-Image /RestoreHealth and then sfc /scannow.

    You mean that the symptom is that a mixture of web and desktop on the same chat causes background color glitches? For both types or only for one?

There currently isn't a good answer to this question.

The issue has successfully been reproduced with Office 365 Premium Support and after walking through all the already tried solutions, escalated to the Teams Engineering team.

They confirm that none of the options above seem to work and hope to provide a fix or solution soon.
