Thank you for testing my patch. You are correct, your output is the same as
mine so I think that Skia isn't converting pixels. So, I think the next place
for me to investigate is the code where Skia copies its bitmap pixels to the
screen.

>From what I can see, Skia creates a macOS CAMetalLayer to each LibreOffice
NSView and draws to the CAMetalLayer. macOS then copies the CAMetalLayer to the
screen in -[NSWindow displayIfNeeded] so maybe the CAMetalLayer has an
unexpected pixel format or colorspace Skia does not know how to convert to. 

I will post another debug patch in the next day or so.
