This is a common issue that many organizations have encountered. Here are some troubleshooting steps and potential remedies to help narrow down the issue:

1. Check Teams Client Version:

 • Ensure that employees are running the latest version of Microsoft Teams. Microsoft frequently releases updates that address performance and video issues.

 • If users are on the Teams desktop app, consider trying the web version of Teams (in an up-to-date browser) to see if the problem persists.

2. Hardware Acceleration:

 • Hardware acceleration in Teams can sometimes cause video rendering problems.

 • Ask affected users to disable hardware acceleration:

  – Click on the profile picture in Teams.

  – Go to Settings > General.

  – Uncheck “Disable hardware acceleration” (or if it says “Enable hardware acceleration”, toggle it off if it’s causing issues).

  – Restart Teams and test again.

3. Update Graphics Drivers:

 • Outdated or incompatible graphics drivers can lead to video issues.

 • Verify that the laptops have the latest graphics drivers installed. Check with the device manufacturer (or use Windows Update if supported) for any recent updates.

 • It might also be worthwhile to check if there are any known issues between the current graphics driver version and Windows 11 24H2.
