Here is how to reproduce the problem: play any file that is HEVC-encoded using the BT.709 colorspace. Force Direct Stream. The problem also happens using Direct Play if the file was originally in an MKV container with color information in the header.
Here is how to make the problem go away: If the file was in an MP4 container, force Direct Play. if it was in an MKV container, remove the color information with a tool like MKVToolNix, and then force Direct Play.
