OpenVidu crops video stream

Hi all,

I have an issue with the video stream OpenVidu shows in the browser.
In the image I provided the orange “window” is what my camera is showing when i use any other App (Windows Camera App, Microsoft Teams). When I use OpenVidu the edges get cut off & I only see the yellow “window”. This happens on our own Server & also on the offical OpenVidu Demo.

Does anyone know why this happens?

Thanks in advance for your assistance!

This is about css.
