1675191 - sw-wr: cnn.com election map is not rendered

Status: RESOLVED DUPLICATE of bug 1674154

(Core :: Graphics: WebRender, defect)

Description

[Chris Peterson [:cpeterson]]

Attachment: CNN_map_screenshot.jpg

When gfx.webrender.software is enabled, CNN's interactive election map of the United States is not rendered:

https://www.cnn.com/election/2020/results/president

See the attached screenshot. I initially tried to take a screenshot with Firefox's built-in screenshot tool, but the screenshot image produced rendered the map even though the rendered web page did not.

I can reproduce this bug in 84 Nightly and 82 Release, so this is not a recent sw-wr regression.
