I’m experiencing slight color flickering in grey areas of the image of HDR videos, for instance the clouds in this sample. You’ll see red and green pixilation pulsing in a regular pattern, like the decoder doesn’t know what color it should be.
I’ve come across it in other HDR files as well (also only in grey areas). It’s not present when using the software decoder or viewing the file through the player of my TV. (LG OLED 55B6)
I’ve not noticed it in SDR footage.
