Rain-like noise in 4K movies

Apparently the refresh rate on start stop didn’t work?

I don’t understand the whitelist thing. Sorry.

On the screen picture it seems that you have “Sync playback to display” enabled, that should be disabled.
Also did you changed the GUI back to 1980p?

No, “Sync playback to display” wasn’t enabled (I see why it looks that way on the photo).
And when I go back to the Display > Resolution and turn it to 1920 the “rainy noise” comes back.

I tried 1920x1080p and this one also fixes the problem. So it’s only with 1920x1080i.

We had a problem before when a user set the GUI to an interlaced mode. Avoid this for now.
