Topic: YUV/4:2:0/10 bits problem?

Anyone else having problems with YUV420p10 content? YUV420p8 works fine. The codec doesn't matter, happens with h265 and h264.
For me it looks like this:
https://0x0.st/scn-.pn
(latest SVP 4 on OSX with self-built mpv, around 1 week old)

Nothing suspicious in SVP's log:

13:16:49.943 [i]: VideoPlayer: mpv connected, waiting for the video info...
13:16:50.474 [i]: VideoPlayer: mpv 0.28.0-212-gd7db42d
13:16:50.502 [i]: Media: video 1920x1080 [PAR 1.000] at 25.000 fps [constant]
13:16:50.502 [i]: Media: codec type is HEVC, YUV/4:2:0/10 bits
13:16:50.515 [i]: Playback: starting up...
13:16:50.520 [i]: Playback [1e7e0c8a]: resulting video frame 1920x1080
13:16:50.521 [i]: Playback [1e7e0c8a]: 4 acceptible profiles, best is 'NOOP' [999]
13:16:50.523 [i]: Playback [1e7e0c8a]: enabled while video is paused
13:16:50.524 [i]: Profile: using auto values [1]
13:16:50.525 [i]: Playback [1e7e0c8a]: playing at 25 [25 *1/1] /10 bit
13:17:26.756 [i]: Playback [1e7e0c8a]: disabled while video is paused
13:17:26.757 [i]: Playback [1e7e0c8a]: deleted

NOOP is my profile that doesn't do frame rate conversion but it happens with all profiles.
Happens with and without "allow output in 10 bit color depth".

I asked some other people and it's not a SVP bug, it's reproducible with other means in VS but probably only on mac under unusual circumstances. Will report back when I know more.

Ok MPV will soon get real HDR support I think. They are working on it so the display will turn in the HDR mode.
