1758718 - macOS HDR video reftests render with black pixels for purposes of comparison

Status: NEW

(Core :: Graphics, defect, P3)

Description

[Brad Werth [:bradwerth]]

With all the patches in Bug 1745492 applied, reftests that check the pixels of macOS HDR videos are using pure black pixels for the comparison, which obviously fail.

Two theories:

1. There is a timing issue with how the HDR video is rendered, and the video layer is still black when MozReftestInvalidate triggers.
2. Our capture method can't "see" the HDR pixels because of their placement in a Metal layer.

This is the rendered image when manually/interactively running the reftest image-10bits-rendering-720-video.html. The automated reftest sees only black pixels.
