If you are seeing a green screen, box, or video instead of your Instructor's screenshare, this is likely due to an issue with your graphics card or driver.
Below is an image of what this might look like:
To resolve this, please disable graphics acceleration in your browser. Below are instructions to do this in Chrome. If you are using Edge or Brave, the instructions will be similar.
- Go Chrome's Settings page by clicking on the 3 dots menu at the top-right of the browser, then selecting Settings.
- In the search box at the top, type in "acceleration" and look for the Use graphics acceleration when available option.
- Click the toggle icon for the Use graphics acceleration when available to the OFF position to turn it off. Restart your browser for the change to take effect.
Note: For similar scenarios where your own webcam preview is not rendering correctly--e.g. green screen; video doesn't look correct--disabling graphics acceleration might also fix it.
