Background opacity on images

Hi,

I’m hoping someone can give me a quick answer to something that has been sending me nuts!
Which setting or colour option can remove the opacity from the background fanart when playing music. I prefer the images to be clear rather than “dimmed”.
I seem to have tried every option in the colour settings, but just can’t seem to find the right one.
I have attached an image so you can see.

Incidentally, can I just congratulate marcelveldt on his excellent, constantly evolving skin.
I have tried different skins in the past, but always come back to this one.
Thank you in advance
