Changing opacity for the note texture doesn't change anything on the video

I just upgraded to the 4.7.4 version and I just realized that even if you lower the opacity for the note texture, it doesn't change anything and it stays at an opacity of 100 on the video. I tried on another computer and it does the same thing.

Best regards.
