color hue changing

[yang299kms]

i noticed that sometimes after playing movies for many hours that suddenly the hue would change, sometimes it tilts toward greenish faces or sometimes redish faces. if i stop the movie and resume everything is back to normal for awhile longer. I don't see any kind of errors in the log at all, this is w/ the latest git build hash 5d0aa9393d55f4cc8e02a9b49842443a9ac95b25, also noticed it w/ previous builds but never really bothered me that much.

1080 or 720 display ?
M1 or M3 ?
What types of movies ? local server or streaming addons ?
What format movies, h264, mpeg2, vc1 ?

/sys/class does contain a hue adjustment but we don't touch it.

1080p display on M1. These are h264 in mkv container with ac3 or dts sound. Playing from my nas using nfs. It doesn't always happen, just if I'm playing movies for an extended amount of time.

correct, not hue but saturation.

cat /sys/class/video/saturation

generally, you can cat anything in /sys/class/xxx

does 720p display do the same ?
