Switched from Nightly to DevEd to check and can't reproduce it there like it was before.

Would be good to get a regression range here, plus to confirm that it's related to Angle (by setting "gfx.webrender.force-angle=false" in the prefs).
It's unlikely the bug in WR itself, but rather in the facilities that provide GL context to it (Gecko GLContext, Angle, driver, etc).

The issue does not appear to be specific to Windows or AMD (or mpv), as I'm seeing what I presume to be the same issue on a MacBook Pro (early 2013) using Intel HD Graphics 4000 with latest Nightly on Catalina. The colours go back to normal if I force the separate NVIDIA GeForce GT 650M to be used instead of the Intel HD Graphics, however. Setting "gfx.webrender.force-angle" to false does not appear to have made a difference.

It affects both page content and browser chrome, as shown in the attachment. Only blue and red colours appear to get inverted, with green and grayscales seemingly unaffected.

This is a separate issue - see bug 1572843

Either latest Windows 10 update or installing fresh driver from amd website instead of old driver from manufacturer fixed issue for me.

Jessie, since this may be resolved by a driver update do you want to wontfix the bug? Or is there some work for us to do here?

Wontfix is good
