Colors are distorted in MP4 video as you can see in the attached screenshot. The distorted colors impact video on many sites including,,,, etc. They do not impact which displays video correctly. My Firefox version is 68.10.0esr (64-bit) and my OS is RHEL 7.8, kernel version 3.10.0-1127.13.1.el7.x86_64, Gnome Version 3.28.2

I have tried running in safe mode but the issue persists.

How do get Firefox to display MP4 video with correct colors?

To my knowledge this may happen as combination of system codecs and nVidia proprietary drivers on some machines. If I recall correctly tests I've done the RGB color space gets incorrectly detected as BGR (with alpha). If this is true there is nothing Mozilla can do about it and problem lies between nvidia drivers VS system codecs (in my case it was oneplay gstreamer pack).
