[Tracking Requested - why for this release]:
This website is entirely black with Firefox 79.0 (build 20200720193547) if WebRender is disabled.
(In comparison, Google Streetview is not black.)

I also confirmed the problem on nightly and beta on my Windows PC. I did not see the problem with WebRender.
:jgilbert, can you comment to the bug?

As far as we can tell, this issue is limited only to this one site. Not tracking for 81.
