Last update of Firefox only shows a small subportion of the video on YouTube

It used to work really good, but now it just now was auto updated to version 129.0 and only a small portion of the video is visible in the viewport (less than a quarter?). Wish you could easily downgrade versions in Android.

I suspect that it is displayed wrongly when it is an HDR video, it is normal on some videos and on some other sites. But a lot of newer videos are blown out..
