opengl-hq debanding doesn't work with OS X hwdec (videotoolbox)

[kiririn]

Not sure if it's even supposed to work but examples are below. I took the screenshots with Ctrl+s.

With hwdec:
mpv [HorribleSubs]\ Non\ Non\ Biyori\ Repeat\ -\ 04\ [720p].mkv --no-config --start=14:39 --pause --vo=opengl-hq --hwdec=auto

Without:
mpv [HorribleSubs]\ Non\ Non\ Biyori\ Repeat\ -\ 04\ [720p].mkv --no-config --start=14:39 --pause --vo=opengl-hq

Version: mpv git-0af5335

It's supposed to work.

What about mpv file.mkv --vf=format=nv12 --vo=opengl-hq?

What about mpv file.mkv --vf=format=nv12 --vo=opengl-hq?

That doesn't really do anything that I can see but if I add --hwdec=auto I get this:

Anyway, post log with -v and videotoolbox.

Thanks. The output looks as expected, so I suspect a subtle issue with the use of texture rectangles. (The only thing different to the sw case.)
