Annoyingly it seems Linux doesn't know the subpixel order of my monitor (DRM_MODE_SUBPIXEL_UNKNOWN). And Google seems to suggest this is pretty common, because the information isn't available in EDIDs. So I can't easily test any fix for nested just yet.
What I can do however is look at support for /setting/ the subpixel order. Since it seems that's what most people will need to do. We may also want to consider defaulting to HRGB if it's unknown.
