does this happen on all clients for the same video(s)? (Browsers/computers/phones/tvs)
Yeah, I usually check this stuff but the only place I watch the videos on my Jellyfin server is my PC. Though my kid never said anything about color washing on her devices and she watches them on like 5 different devices.
does this happen for all videos on the affected client(s)?
So do, some don't. It was mostly 265 that was giving me issues. Though 264 would do it from time to time.
What color is the color wash?
Green, blue, sometimes red.
Sounds like the video is using some kind of encoding that the client isn’t handling correctly.
That's what was confusing me because it was the official server and the official client giving me issues.
Delfin seems to be ok though it's GUI is kinda poop.
